Answer:
The nucleotide sequence of a DNA codon is TAG. In an mRNA molecule transcribed from this DNA, the codon has the sequence 5'-<u>AUC-3'</u>. In the process of protein synthesis, a transfer RNA pairs with the mRNA codon. The nucleotide sequence of the tRNA anticodon is <u>3'-UAG-5'</u>. The amino acid attached to the tRNA is <u>Isoleucine</u>.
Explanation:
In the process of protein synthesis the mRNA contains the sequence of nucleotides —transcribed from the DNA— that defines the sequence of amino acids that a synthesized protein will have.
Codons are triplets of nitrogenous bases present in mRNA, which encode an amino acid, as well as the start and end of protein synthesis.
Anticodons correspond to triplets of bases present in transfer RNA (tRNA), which correspond with mRNA codons. tRNA is responsible for coupling amino acids to the polypeptide chain being synthesized. In view of this:
<em>- DNA triplet: TAG</em>
<em>- Codon mRNA: 5'-AUC-3'
</em>
<em>- Anticodon tRNA: 3'-UAG-5'</em>
<em>- Amino acid: Isoleucine</em>
RNA synthesis depends on RNA polymerases (RNAPs). This is the enzyme
that faciliates copying a sequence of DNA which is the first step
leading to gene expression. This multi-step process is important for
researchers to understand especially in relations to studying how
genetics influence disease processes.
There are many types of natural selection like direct selection, disruptive selection and stabilizing selection.
The situation given is that a population of mice lives in a city. The largest mice tend to be killed by predators and the smallest mice cannot compete for food.
The type of selection here is stabilizing selection. It is a type of natural selection in which there is decrease in genetic diversity as the population stabilizes.
