Null mutation would cause ABC mRNA to be delivered to the correct location but not translated is EIF2B. Null mutation refers to a mutation that completely abolishes the function of a gene by disrupting the gene's coding sequence or regulatory elements. In other words, if a null mutation occurs in a gene, the gene product will not be produced.

There are several genes that could potentially be involved in this scenario, but one strong candidate is a gene called EIF2B. EIF2B encodes a complex of proteins that is essential for the initiation of protein translation. Specifically, the EIF2B complex is required to catalyze the exchange of GDP for GTP on the translation initiation factor eIF2, which is necessary for the assembly of the ribosome and the initiation of protein synthesis.

If a null mutation occurs in EIF2B, the eIF2B complex will not be functional and translation initiation will be impaired. This could lead to a situation where ABC mRNA is correctly transported to the site of translation (i.e. the ribosome), but the initiation of protein synthesis is blocked and ABC protein is not produced.

There may be other genes or factors involved in this process as well, and there may be other scenarios that could also lead to ABC mRNA being delivered but not translated. However, based on the information provided in the question, a null mutation in EIF2B seems like a reasonable answer.

Answer:

The ethics of artificially inserting traits in animals has been in the practice for years in the form of selective breeding, but should scientists really be editing DNA to the extent they are today? I don't believe they should. Life itself should construct itself without us interfering. Making a brand new plant just because it looks nice doesn't account for many factors, including the fact that it could be harmful to nearby plants if pollinated. In addition, generic engineering costs quite a lot of money, which should be used on other more cost effective methods, such as improving agriculture rather than creating a whole new plant that could harm entire crops. Genetic engineering isn't a necessity and humans should not play God with plant and animal life.

Fight or flight refers to the physiological response to a threat in which the autonomic nervous system prepares the body for fighting or escaping. Option B is Correct.

The fight-or-flight reaction, which is characterized by bodily changes, including neurological and endocrine alterations that prepare a human or an animal to react or to withdraw, is a response to an immediate danger to survival (Britannica, 2019).

To put it another way, it is what our body does in response to a threat. An environmental or psychological stressor can set off a chain reaction of stress hormones that alters the body's physiology. The "fight or flight" reaction is an acute stress response that is brought on when the sympathetic nervous system is activated in this way. Option B is Correct.

To calculate the allele frequency in the population, we divide the number of occurrences of the particular allele by total number of all alleles in the population Allele frequencies can be represented as a decimal, a percentage, or a fraction.

Given the population of white (W) and black (w) sheep, 22 out of 244 sheep are black, the frequency of the dominant allele in the population = 222/244×100=

More camouflaged individuals have the better chances of survival until all the individuals that remain are all well camouflaged.

The term natural selection implies that organisms that we well adapted to their environment tend to survive better and have the opportunity to reproduce. This is based on the principle of the survival of the fittest.

These organisms tend to pass on these favorable traits to their offspring and thus the gene pool is changed as only the organisms that have these favorable genes remain.

If camouflage helps an organism to survive better in its habitat, then it follows that more camouflaged individuals have the better chances of survival until all the individuals that remain are all well camouflaged.

Referring to the picture, we can conclude that the picture J will have the most effect on ocean tides.

Whichever model is similar to model J in the picture will be your answer.

Hoped this helped.

\(BrainiacUser1357\)

The model that shows the positions of the Sun, Moon, and Earth that have the greatest effect on ocean tides is the spring tide model.

During spring tides, the Sun, Moon, and Earth are in alignment, which causes the gravitational pull of the Sun and Moon to reinforce each other, leading to higher high tides and lower low tides.

Spring tides occur twice a month, during the new moon phase and the full moon phase.

In contrast, neap tides occur when the Sun, Moon, and Earth form a right angle, which causes the gravitational pull of the Sun and Moon to counteract each other.

This leads to lower high tides and higher low tides. Neap tides also occur twice a month, during the first and third quarter moon phases.

It's important to note that the positions of the Sun, Moon, and Earth aren't the only factors that affect ocean tides. Other factors, such as the shape of the coastline and the depth of the ocean floor, can also influence the height and timing of tides in a particular area.

Answer: However, most non-canonical genetic codes are inferred from DNA sequence alone, or occasionally DNA sequences and corresponding tRNAs. Because the code governs the translation of nucleotide to amino acid sequences, a code can in principle only be confirmed when both the gene and protein sequences are known

Explanation :DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... Every living organism uses that same system. Basically, every three pieces of DNA becomes one amino acid.

DNA is able to mutate and change the structure and/or function of an organism. The correct option is B.

A polymer made of two polynucleotide chains that coil around one another to form a double helix is called deoxyribonucleic acid.

All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid.

All of the living things on Earth share the same genetic code, with a few small exceptions.

Yes, mammals co-existed with dinosaurs. During the time of the dinosaurs, mammals coexisted with these large reptiles.

However, the extinction of the dinosaurs, which is believed to have been caused by a combination of an asteroid impact and volcanic activity, had a significant impact on the Earth's ecosystems.

With the disappearance of the dinosaurs, there were many new ecological niches available for other organisms to occupy.

Mammals, which were typically small and active at night during the dinosaur era, were among the beneficiaries of this shift.

They began to diversify and adapt to the new ecological opportunities created by the dinosaur extinction event.

As a result, they evolved into a wide range of different forms and sizes, occupying various ecological roles.

This diversification and evolution of mammals after the dinosaur extinction led to the emergence of many new groups of mammals and contributed to the development of the wide variety of mammals that exist today.

Thus, the extinction of dinosaurs played a key role in shaping the evolutionary history of mammals.

During the Guides phase of HIV disease, the insusceptible framework turns out to be seriously compromised, prompting a pattern of progressively extreme side effects. This cycle happens because of the accompanying elements:

Declining CD4+ Lymphocytes: HIV explicitly targets and obliterates CD4+ White blood cells, which assume a pivotal part in planning a safe reaction. As the infection duplicates and contaminates more CD4+ Lymphocytes, their numbers decline, debilitating the insusceptible framework's capacity to actually ward off diseases and sicknesses.

Pioneering diseases: With a debilitated insusceptible framework, people with Helps become defenseless to deft contaminations. These are contaminations brought about by organic entities that normally don't cause extreme disease in individuals with sound safe frameworks. Deft contaminations can go from bacterial, viral, parasitic, and protozoal diseases. These diseases can be extreme, relentless, and testing to treat, adding to the deteriorating of side effects.

Industrious aggravation: Persistent safe actuation and irritation are signs of HIV contamination. The continuous insusceptible reaction and aggravation further harm the safe framework and imperative organs after some time. This tireless irritation can prompt the advancement of unexpected complexities, like cardiovascular illness, neurological issues, and certain malignant growths, which add to the movement of side effects.

HIV transformations and viral variety: HIV has a high change rate, prompting the improvement of viral variations that can dodge the safe framework and antiretroviral treatments. As the infection advances, it turns out to be harder to control and treat, adding to the deteriorating side effects and treatment challenges.

Generally speaking, the pattern of progressively extreme side effects during the Guides phase of HIV contamination is driven by the dynamic obliteration of the safe framework, powerlessness to shrewd contaminations, persevering aggravation, and viral changes that compromise the body's capacity to protect against contaminations and illnesses.

A boy inherits 25% of his nuclear DNA from his paternal grandmother.

This is because he receives half of his nuclear DNA from his father, who received half of his nuclear DNA from his own mother. Therefore, the boy has inherited one-quarter of his nuclear DNA from his paternal grandmother.

Each human cell contains two sets of chromosomes - one set inherited from the mother, and one set inherited from the father. The nuclear DNA is contained within these chromosomes.

When a baby boy is conceived, he inherits half of his nuclear DNA from his biological mother, and half from his biological father. The father, in turn, inherited half of his nuclear DNA from his own mother (the boy's paternal grandmother), and half from his own father (the boy's paternal grandfather).

Therefore, the fraction of a boy's nuclear DNA that is inherited from his paternal grandmother is 1/4, or 25%. This is because the boy's father inherited half of his nuclear DNA from his own mother (the boy's paternal grandmother), and then passed on half of that DNA to the boy. So the boy inherits 1/2 x 1/2 = 1/4 of his nuclear DNA from his paternal grandmother.

-----------------------------------

For this gene we will assume complete dominance, meaning that the dominant alele completely hides the expression of the recessive allele.

According to this information, we can say that

Genotype      Phenotype

HH                  Hairy pig

Hh                   Hairy pig

hh                   Hairless pig

9) Geneviene does not have hair  ⇒  Its genotype is hh

10) Fred has hair ⇒ Its genotype is HH or Hh

Possible crosses

11 and 12)

Cross1: If Fred was genotype HH and bred with Genevieve

Parentals) HH    x    hh

Gametes)   H   H    h    h

Punnett square)    H    H

                        h   Hh   Hh

                        h   Hh   Hh

F1) 100% of the progeny is expected to have hair and be heter0zyg0us, Hh.

13 and 14)

Cross2: If Fred was genotype Hh and bred with Genevieve

Parentals) Hh    x    hh

Gametes)   H   hh    h    h

Punnett square)    H    h

                        h   Hh   hh

F1) 50% of the progeny is expected to have hair and be heter0zyg0us, Hh.

     50% of the progeny is expected to be hairless and be h0m0zyg0us recessive, hh.

15)  

• If the individual with the unknown genotype (Fred) is heter0zyg0us, the phenotypic rate of the descendants is 50% heter0zyg0us -Hh- and 50% h0m0zyg0us recessive -hh-.

• But if the individual with the unknown genotype is h0m0zyg0us dominant, the phenotypic rate of the descendants is 100% heter0zyg0us for the trait, Hh.  

16)

The weakness is that even if Fred is heter0zyg0us for the trait, when making the cross it might occur that all individuals in the progeny are born h0m0zyg0us recessive, and there is a risk of missinterpreting the results.

So in that situation, many crosses must be done between fred and genevieve to se sure about Freds genotype.
