What's the new peptide chain when the new DNA segment is translated?
saveliy_v [14]

Answer:

The correct answer is - Methionine, serine, histidine, aspartate, glycine

Explanation:

The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.

New DNA strand: 3'-TACAGGGTGCTACCCACT-5'

mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'

The translation of this mRNA would be on the basis of chart

AUG - Methionine (start codon)

UCC - serine

CAC - histidine

GAU - aspartate

GGG - glycine

UGA -  stop codon

The peptide chain would be - Methionine, serine, histidine, aspartate, glycine
