Question

the diagram below shows a polypeptide chain folding to become a protein with a compact, 3 -dimensional structure. the final shape of a protein is determined by the sequence of its amino acid residues. what determines this amino acid sequence? a. the number of nucleotides in the polypeptide b. the number of nucleotides in the dna template c. the sequence of nucleotides in the polypeptide d. the sequence of nucleotides in the dna template

Explanation:

The DNA sequence serves as a template for protein - synthesis. Through transcription and translation, the sequence of nucleotides in the DNA template is used to determine the sequence of amino acids in a polypeptide chain (and thus the protein). The number of nucleotides is not what determines the amino - acid sequence, but rather their specific order. Polypeptides do not have nucleotides (they are made of amino acids), and it is the DNA template's nucleotide sequence that matters.

Answer:

D. the sequence of nucleotides in the DNA template
