the final amino acid in a polypeptide chain is encoded by a codon near the ______.
Answers
A codon located close to the 3' end of the mRNA encodes the last amino acid in a polypeptide chain. Each of the remaining 19 amino acids is designated by two to six codons.
The stop codons, UAA, UAG, and UGA, are used to indicate when translation has finished. A codon is a triplet of nucleotides that codes for an amino acid. One amino acid is encoded by each set of three nucleotides. In mRNA, each trio of bases forms a codon, and each codon designates a certain amino acid (thus, it is a triplet code). Thus, the chain of amino acids that makes up a protein is assembled in order using the mRNA sequence as a template.

Answer: Streams, rivers, watersheds, and stream tables to model their evolution. Watersheds are where water collects and where water flows to the oceans. However, streams and rivers are not just water. They include particles: sand, clay, soil, and more; which are suspended in the water and move with the current or sink to the bottom. Either way they pile up as sediment or erode the river bed as they move, changing the flow and shape of the rivers, streams, and watersheds over time. This can create serious consequences for safety, erosion, production of energy and recreational opportunities; all of which affect the quality of life and health of organism who depend on stream, river, and watershed environments. Knowledge of how water flows and it interactions in streams, rivers, and watershed is also important for our understanding of ecosystems to preserve, restore, and prevent their degradation.

which krebs cycle intermediate can move from the mitochondria into the cytoplasm to become the initiator of fatty acid synthesis
Answers
Citrate can move from the mitochondria into the cytosol, where citrate lyase cleaves it into oxaloacetate and acetyl-CoA, the ini- tiator of fatty acid synthesis.
Citrate is produced within the Krebs cycle from oxaloacetate and acetyl-CoA by citrate synthase (CS). it can be exported from the mitochondria through citrate carrier (CIC). Cytosolic citrate is broken down by ACLY to oxaloacetate and acetyl-CoA. Acetyl-CoA may be used as a substrate for fatty acid synthesis.
as an example, citrate, a TCA cycle intermediate, can pass across the mitochondrial membrane to the cytosol, in which it's far cleaved into OAA and acetyl CoA to aid a selection of biosynthetic methods, which include the synthesis of fatty acid and sterols.

is the following statement true or false? the tissue of the peristome in a moss is haploid.
Answers
The given statement, "The tissue of the peristome in a moss is haploid," is false because the peristome is diploid.
In mosses, the peristome is a specialized structure found in the capsule, which is the sporangium or the part of the moss that produces spores. The peristome is responsible for the controlled release of spores. It consists of specialized teeth or appendages that open and close in response to humidity changes, dispersing the spores.
The cells that make up the peristome teeth are derived from the diploid sporophyte generation of the moss life cycle. The sporophyte generation is diploid, meaning it has two sets of chromosomes. These cells undergo meiosis to produce haploid spores, which are released by the peristome.
Thus, the spores themselves are haploid, but the tissue of the peristome that produces and releases the spores is diploid.

Most fields that are irrigated year after year will eventually build up salt in the soil as water regularly evaporates and leaves some salt behind. One way farmers minimize this salt build up is to flood their fields every few years before planting. This flood water leaches out the salt in the soil. What advantages and disadvantages do you see in this approach?
Answers
Answer:
An advantage is that the salt will be washed out and a disadvantage is that it still leaves some salt behind
Explanation:
Irrigation is an agriculture practice which includes watering the cropland, this practice is advantageous as it washes the salt out of the soil however, some amount of salt still remains which affect the concentration of salts in soil.
What is irrigation?
Irrigation is the agricultural process which includes applying the controlled amounts of water to the land to assist the production of crops, as well as to grow the landscape plants and lawns in the agriculture lands. It may be known as watering in lawns. Agriculture which does not need irrigation but relies only up on the direct rainfall is referred to as rain-fed agriculture.
An advantage of the approach used in this case is that the salt will be washed out of the soil and a disadvantage of this approach is that it still leaves some salt behind in the soil which decreases the diffusion of water through roots due to increase in concentration of soil.

which structure includes all others in the list: er, vesicle, endomembrane system, nuclear envelope?
Answers
The structure includes all others in the list: er, vesicle, endomembrane system, nuclear envelope is the endomembrane system
The endomembrane system is an organelle system that is in charge of modifying, packaging, and transporting proteins and lipids. This system has a structure that is made up of a complex network of membranes that includes the nuclear envelope, ER, Golgi apparatus, lysosomes, and vesicles. They all work together to transport proteins and lipids from one part of the cell to another. The endoplasmic reticulum (ER) is a large organelle that is the most extensive part of the endomembrane system, it consists of a system of membrane-bound tubes and sacs that are involved in the synthesis and modification of proteins and lipids.
The vesicle is a small membrane-bound sac that moves proteins, lipids, and other substances around the cell and vesicles can form by budding off from the ER or Golgi apparatus.The nuclear envelope, also called the nuclear membrane, is a double membrane that encloses the nucleus, it has pores that allow molecules to move in and out of the nucleus. The nuclear envelope is continuous with the ER, and so it is part of the endomembrane system. In conclusion, the endomembrane system includes the ER, vesicle, and nuclear envelope.

What do you need to add to the growth medium specifically to make that work?X-galTiantibioticIPTGglyphosate
Answers
In order to make the growth medium work, there are several specific substances that need to be added such as X-gal, tiantibiotic, IPTG, and glyphosate
First, X-gal is often added to the growth medium as a substrate for beta-galactosidase, an enzyme that is used to screen for the presence of recombinant DNA. Additionally, a tiantibiotic is often added to the growth medium to select for bacteria that have taken up the recombinant DNA. IPTG is also commonly added to the growth medium as an inducer of protein expression, this molecule binds to a transcriptional repressor, causing it to fall off of the promoter region of a gene of interest, allowing for its transcription and translation into protein.
Finally, glyphosate is sometimes added to the growth medium as a selective agent to kill off bacteria that do not contain the desired recombinant DNA. Overall, these substances work together to create a growth medium that allows for the selection and amplification of bacterial cells containing recombinant DNA.

Explanation:
The purpose of DNA extraction liquid is to break open cells and dissolve cellular membranes, proteins, and other cellular components in order to release DNA from the cell. This is an essential step in DNA extraction procedures, as DNA is tightly packed within the cell and needs to be isolated and purified for further analysis.
There are many different types of DNA extraction liquids that can be used depending on the type of sample and the downstream application. Commonly used extraction liquids include phenol-chloroform, ethanol, and various commercial kits that utilize a variety of chemical agents and protocols.
The DNA extraction liquid typically contains a combination of reagents that help to disrupt the cell membrane and denature cellular proteins, allowing the DNA to be released and separated from other cellular components. These reagents can include detergents, salts, enzymes, and organic solvents. After the DNA has been released from the cell, it can be further purified using various methods, such as precipitation or column-based purification, depending on the specific application.
In summary, the purpose of DNA extraction liquid is to break open cells and release the DNA for further analysis. It is a critical step in many molecular biology and biotechnology applications, including genetic research, diagnosis of genetic diseases, and forensic analysis.

Twenty four percent of the bases of a double- stranded DNA molecule are adenine (A). What percentage of its bases would be expected to consist of guanine (G)
Answers
If the percentage of adenine bases is 24% then the guanine base percentage will be 26% according to Chargaff's rule.
DNA consist of millions of base pairs in the form of purines [Adenine (A) Guanine (G)] and pyrimidines [ thymine (T) cytosine (C) and uracil (U only in RNA in place of T).Adenine is complementary to thymine and uracil while guanine is complementary to cytosine.According to Chargaff's rule ( A + G = T + C ), DNA from all cells of all creatures should have a 1:1 ratio of pyrimidine and purine bases. More specifically, the amounts of guanine and adenine should be equal to cytosine and thymine, respectively.
hence if the percentage of Adenine (A) is 24% then the complementary base Thymine (T) will also be 24%
Now A + T = 24 + 24 = 48% out of 100
the remaining 52% is composed of GC i.e., 26 % + 26%
Hence Guanine will be 26%
Finally, A + G = T + C --------> 24 + 26 = 24 + 26

When we are talking of DNA, genes, we must remember that when a gene is transcripted to primary RNA it is formed by two types of segments, exons, and introns. Those coding are exons and those not coding are Introns. About these last (introns) there has been a wide discussion about its function, there are some who even call it junk DNA. Their function is not quite understood yet, there has been a recent increase in the interest in these noncoding sequences and several hypotheses regarding their function in the chromosome. It has been proposed that introns could motivate recombination and remotion of certain genetic groups through the evolutive process, recent evidence indicates that Introns contribute to maintaining stability, sometimes suppressing the activity of other genes, helping in the evolutive process.
