How many nucleotides are required to code for a protein consisting of 450 amino acids?
A
1350 nucleotides
B
150 nucleotides
C
450 nucleotides
D
900 nucleotides
Verified step by step guidance1
Recall that each amino acid in a protein is coded by a sequence of three nucleotides called a codon.
Identify the number of amino acids in the protein, which is given as 450 amino acids.
Use the relationship between amino acids and nucleotides: the total number of nucleotides required is the number of amino acids multiplied by 3.
Write the formula: $\text{Number of nucleotides} = 450 \times 3$.
Calculate the product to find the total number of nucleotides needed to code for the protein.
