O
A. Glycine-histidine-glycine-glycine
B. Histidine-glycine-glycine-glycine
O
C. Histidine-glycine-glycine-tyrosine-glycine
D. Glycine-glycine-tyrosine-glycine-histidine

Answer 1

Answer: D. Glycine-glycine-tyrosine-glycine-histidine.

Explanation: The mRNA synthetized during transcription is the template for protein translation. Each triplet or codon in mRNA codifies an aminoacid of the protein:

GGU: Glycine

GGC: Glycine

UAC: Tyrosine

GGG: Glycine

CAU: Histidine

The sequence of the protein translated will be: Glycine-Glycine-Tyrosine-Glycine-Histidine.
