vitfil [10]

Answer:

The correct answer is -

gly-met-arg-phe-val-pro

Explanation:

The production of the amino acid chain or sequence from the desired DNA sequence is called the protein synthesis or central dogma that involves two processes, transcription and translation. Transcription is the process of transcribing the information encoded in the DNA sequence into a complementary mRNA sequence. The translation is the second process that involves the translation from mRNA to a specific amino acid.

mRNA sequence is complementary to the DNA

so, DNA - CCC-TAC-CGC-AA-CG-CC

mRNA - GGG-AUG-CGC-UUU-GUC-GG

and amino acid from the chart : gly-met-arg-phe-val-pro
