Question

After transcription occurs, an mRNA transcript enters the cytoplasm. A short section in the middle of the transcript has the following codon sequence: GUCCCUGGG. What is the sequence of amino acids that would be translated from this section of the mRNA transcript?
Choose one:
A. CAGGGACCC
B. Gln-Gly-Pro
C. Leu-Ala-Asp
D. Val-Pro-Gly

Answer 1

Answer:

The correct answer will be option-D

Explanation:

The process of protein synthesis is known as translation which translates the sequence of mRNA into proteins. This takes place in the ribosome in every organism where the tRNA brings the amino acids corresponding the triplet of the nitrogenous base the tRNA reads in the mRNA.

The triplet of the nitrogenous bases which codes for the specific amino acid is known as a codon. Each codons code for a specific amino acid which brought by the tRNA gets attached to the nascent peptide via peptide bonds.

Since GUC codes for Valine, CCU codes for proline and GGG codes for glycine, therefore, valine-proline-glycine is the correct answer.
