The nucleotide sequence of a DNA codon is TAG. In an mRNA molecule transcribed from this DNA, the codon has the sequence _______
inna [77]

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>

How does an organisms growth compared to the growth of an icicle
Travka [436]
