Question

The codon chart shown here uses the three base sequence found on the mRNA molecule after the information is copied from DNA during transcription. Imagine that a protein is being assembled at the ribosome. What is the amino acid sequence for the codons GUU AAA?

A) valine - lysine
B) leucine - lysine
C) valine - arginine
D) leucine - arginine

Answer 1

i think its A)valine-lysine

Answer 2

Ans.

Codon may defined as a sequence or code made up of three nucleotide bases. There are total 64 codons, made up from different combinations of nucleic acid bases (A, G, C, T). Each codon codes for a specific amino acid. The amino acid coded by GUU codon is valine and amino acid coded by AAA codon is lysine.

Thus, the correct answer is option 'A). valine-lysine.'
