Question

The Tobacco mosaic virus capsid is composed of a single type of protein, 158 amino acids in length. How many nucleotides are required to code for the protein?

• A. 632
• B. 474
• C. 158
• D. 316

Answer 1

Answer:

B. 474

We know, 1 amino acid is encoded by 3 nucleotides. Given, Length of capsid protein of Tobacco mosaic virus = 158 amino acids Therefore, number of nucleotides required to encode the protein = 158*3 = 474
