Question

If a specific gene code for a polypeptide is 120 amino acids long, approximately how many nucleotides long is the mRNA that codes for this polypeptide?

Answer 1

Answer: 360

Explanation: 120 x 3 = 360.

Answer 2

360 nucleotides

Step-by-step explanation:

Each amino acid corresponds to a specific codon, a sequence of three DNA or RNA nucleotides.

If there are 120 amino acids and a sequence of three nucleotides corresponds to one amino acid, then 120 × 3 = 360 nucleotides.

Hope that helps.
