A segment of DNA is known to contain the following base sequence:3' GATACCTTTGTGTAGTCATCTT 5'a) Write the mRNA that would be transcribed from this DNA fragment.b) Circle the starter and the stopper in your mRNA sequence. Write the sequence of amino acids which would be encoded in translation. Use the mRNA codon table provided.c) Where in the cell do transcription and translation occur?
Answers
a) In order to transcribe the segment of DNA, it is important to note that this process is important for gene expression as a protein. An enzyme called RNA polymerase moves along the DNA until the end of the gene, releasing the mRNA. The DNA has two strands: one that goes from 5' to 3' direction, and another one that goes from 3' to 5' direction. The one that's used for transcription will always be the 3' to 5' one, so we already have the correct strand to work with, as it is a 3' to 5' strand.
However, the mRNA will be assembled in the 5' to 3' direction. Using the same complementary base-pairing rules as in DNA, we will pair Cytosine (C) with Guanine (G), but as there is no Thymine (T) in RNA, we will pair Adenine (A) with Uracil (U).
Therefore, the sequence o mRNA read in the 5' to 3' direction is:
5' CUAUGGAAACACAUCAGUAGAA 3'
b) The starter codon is the AUG codon of a messenger RNA (mRNA). Therefore, the sequence of amino acids will start to be decoded there.
The stopper codon can be one of the three following options: UAA, UAG or UGA. In this case, we can only find the UAG codon.
The codons, then will be:
AUG GAA ACA CAU CAG UAG
Then, we can say that the amino acids translated will be:
Met Glu Thr His Gln
(Methionine - Glutamine - Threonine - Histidine - Glutamine
c) In eukaryotes, transcription occurs inside the nucleus of the cell and translation occurs in the cytoplasm.
A researcher experimented with adhesives and glues to find new and stronger adhesives. In 1968, he discovered an adhesive that was very weak rather than strong. The adhesive would stick to paper but it could be removed easily without leaving a trace of adhesive. Because he was trying to find stronger adhesives, the results of that experiment were considered a failure. Several years later, he had the idea of coating paper with the weak adhesive. This meant that notes could be stuck to paper and easily removed at a later time. Today, these removable notes are used by millions of people.

Small pieces of paper with a light stickiness on the back are known as sticky notes, Post-it notes, or repositionable notes. The notes can be repeatedly taken from and reattached to a variety of surfaces and papers thanks to the adhesive.
Canary yellow, three-inch squares were the original form of post-it notes. Sticky notes are available in a wide range of sizes, shapes, and colours nowadays. Every day, people utilise sticky notes all across the world. People always carry and use sticky notes, whether they are at home, at work or in any other setting. Would you consider them to be a brilliant innovation that was created entirely by chance? It is real. Sticky notes were not intentionally invented. Instead, a chemist at 3M Company named Dr. Spencer Silver created a novel, low-tack adhesive in 1968 that could adhere to objects while simultaneously being moved around a number of times. Instead of the super-strong adhesive he was attempting to create, he created a super-weak one.

How can a cell increase surface area without increasing the volume?
Answers
Cells can increase their surface area by folding the plasma membrane. Total cell surface area should increase when a cell divides into two daughter cells.
There are two illustration of membrane supply that support cell division:
(1) unfolding of small surface membrane reservoirs such as microvilli and folds, and (2) exocytosis of intracellular vesicles.
As the cell radius increases, the surface area increases as the radius squared, but the volume increases as the radius cubed (much faster).
Increasing the surface area of the cell increases the amount of material that diffuses into the cell. As volume and surface area increase, volume increases more rapidly, so for every doubling of cell volume, the surface area available for uptake is halved.

Answers
Cell biology: Parts of the cell, Prokaryotic and Eukaryotic Cells.
The Eukaryotic cells are those that have their genetic material within a nucleus. There are three basic types of eukaryotic cells based on their structure: plant cells, animal cells, and fungal cells.
Some of the distinct characteristics of plant cells are:
• The presence of a, cell wall ,composed of ,cellulose, hemicellulose, and pectin,, gives extra protection and support to the cell, and it helps to maintain the shape of the cell.
,• Special pathways of communication are called ,plasmodesmata,, which go through the cell wall.
,• A large central, vacuole,, that serves as, storage, of water and other substances.
• Chloroplasts,, ,produce sugars, using the carbon dioxide available and the energy of sunlight.
They also have other structures common to all eukaryotic cells, such as mitochondria and Golgi apparatus.
Now let's compare this information to the statements:
• Statements a ,and ,b, are, false ,because is the chloroplast that makes sugar using sunlight
,• Statement c is true,, because the vacuole stores many substances, and plant cells also have mitochondria to break down sugar.
,• Statement d is true, because plants and animal cells are two types of eukaryotic cells, and this means they have a nucleus.

Every frog no matter the species if in the same ecosystem is considered part of the same population because no matter if it’s a male/female or has spots or not and etc it’s still a frog.
how is the allele frequency of a population calculated? multiple choice question. the number of individuals that have this allele in the population is divided by the total number of individuals in the population. the number of copies of the allele in the population is divided by the total number of all the alleles for the same gene in the population. the number of copies of the allele in the population is multiplied by the total number of all the alleles for the same gene in the population. the number of copies of the allele in the population is divided by the total number of all the alleles for all genes in the population.
Answers
The allele frequency of a population is the proportion of a particular allele among all the alleles for a particular gene in a population. It can be calculated by dividing the number of copies of the allele in the population by the total number of all the alleles for the same gene in the population. This calculation provides a value between 0 and 1, or as a percentage between 0% and 100%.
For example, let's say there are 100 individuals in a population, and 40 of them have a particular allele for a gene. If each individual has two copies of the gene (one from each parent), then there are 80 copies of the gene in the population. To calculate the allele frequency, we divide the number of copies of the allele (40) by the total number of all the alleles (80), which gives us a frequency of 0.5 or 50%.
It is important to note that the allele frequency of a population can change over time due to various evolutionary forces such as mutation, genetic drift, migration, natural selection, and non-random mating. Therefore, studying the changes in allele frequency over time can help us understand the evolutionary history of a population.

The antibiotics lincomycin A and B are separated by elution chromatography using a bed of cellulose beads with a solvent system of butanol, acetic acid, and water. The total volume of the bed is 100 liters and void fraction is 0.40. The equilibrium constants, K, have been previously measured as 11.0 and 12.0 for A and B, respectively. Estimate the volume of eluate at which the peak will occur for each of these antibiotics.
Answers
To estimate volume of eluate at which the peak will occur for each antibiotic, we need to consider the equilibrium constants (K) and the void fraction of bed. estimated elution volume for lincomycin A is approximately 3.64 liters, while for lincomycin B, it is approximately 3.33 liters.
The equilibrium constant (K) represents the distribution of a solute between the stationary phase (cellulose beads) and the mobile phase (solvent system). A higher K value indicates a stronger affinity of the solute for the stationary phase.
In this case, lincomycin A has an equilibrium constant (K) of 11.0, while lincomycin B has a K value of 12.0. Since lincomycin B has a slightly higher K value, it will have a stronger affinity for the cellulose beads and will take longer to elute from the column compared to lincomycin A.
The void fraction of the bed is given as 0.40, which means that 40% of the total bed volume is occupied by the cellulose beads, while the remaining 60% is the volume available for elution.
To estimate the volume of eluate at which the peak will occur for each antibiotic, we can calculate the elution volume based on their equilibrium constants and the void fraction.
For lincomycin A: Elution volume = Void fraction * Total bed volume / K
Elution volume = 0.40 * 100 liters / 11.0 = 3.64 liters For lincomycin B:
Elution volume = Void fraction * Total bed volume / K
Elution volume = 0.40 * 100 liters / 12.0 = 3.33 liters
Therefore, the estimated elution volume for lincomycin A is approximately 3.64 liters, while for lincomycin B, it is approximately 3.33 liters.
