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

Question

Quizplus · Accepted Answer

Each amino acid in a protein is coded by a set of three nucleotides, known as a codon. Therefore, a protein that is 300 amino acids long would be coded by 300 x 3 = 900 nucleotides. However, since DNA is double-stranded, you would need to double this number to account for both strands, resulting in 1800 nucleotides.
