Question

A particular eukaryotic protein is 300 amino acids long. Which of the following could be the maximum number of nucleotides in the DNA template strand that codes for the amino acids in this protein?

1) 3
2) 100
3) 300
4) 900
5) 1800

Answer 1

A eukaryotic protein that is 300 amino acids long would be coded by a DNA template strand with a maximum of 900 nucleotides, due to the triplet codon requirement for each amino acid.

Step-by-step explanation:

The maximum number of nucleotides in the DNA template strand that codes for a eukaryotic protein that is 300 amino acids long could be 900 nucleotides. This is because each amino acid in a protein is coded by a triplet of nucleotides called a codon. Since there are 300 amino acids, you need 300 triplets, which equals 900 nucleotides (300 amino acids × 3 nucleotides/amino acid = 900 nucleotides).
