A protein is 300 amino acids long.Which of the following could be the number of total nucleotides in the section of DNA that codes for this protein? Remember: DNA is double- stranded.

Question

Quizplus · Accepted Answer

Each amino acid is coded for by three nucleotides, so the total number of nucleotides in the DNA sequence that codes for a 300 amino acid protein would be 300 amino acids x 3 nucleotides per amino acid x 2 strands (since DNA is double-stranded) = 1800 nucleotides. Therefore, the correct choice is C.

A Protein Is 300 Amino Acids Long
