How Many Nucleotides Would Be Expected for a Gene Coding

Question

How many nucleotides would be expected for a gene coding for a protein with 300 amino acids?
A)300
B)100
C)600
D)1200
E)900

Accepted Answer

Each amino acid is coded by a codon, which consists of 3 nucleotides. Therefore, a protein with 300 amino acids would require 300 x 3 = 900 nucleotides.
