The DNA sequence of a gene for a protein:.a. mutates at a high rate. b. is a polymer of four ribonucleotides. c. ultimately determines the amino acid sequence of a protein. d. is a non‑linear code.

The correct answer is : Option C.  ultimately determines the amino acid sequence of a protein

Explanation:

DNA sequence is destined to make a specific amino acid chain of a particular protein through the process of transcription and translation. These two process together known as the protein synthesis.

DNA sequence makes the mRNA sequence and this mRNA sequence with tRNA and ribsomes are used to form the sequence of the amino acid chain   of a protein during protein synthesis.

Thus, the correct answer is option C.
