Step 1/2

The correct answer is option (B) nucleotide sequence in DNA.

Explanation:

Nucleotide sequence in DNA: The nucleic acid sequence in mRNA is determined by the nucleotide sequence in DNA. This process is known as transcription. During transcription, the DNA sequence is used as a template to synthesize a complementary mRNA molecule. The mRNA molecule carries the genetic information encoded in the DNA sequence from the nucleus to the ribosomes in the cytoplasm, where it serves as a template for protein synthesis.

Step 2/2

Explanation for incorrect options

A) The order of amino acids in the protein: This statement is incorrect. The order of amino acids in a protein is determined by the sequence of codons in the mRNA molecule. Each codon, consisting of three nucleotides in the mRNA, codes for a specific amino acid.

Explanation:

C) Nucleotide sequence in RNA: This statement is incorrect. While RNA plays a crucial role in the process of protein synthesis, the nucleotide sequence in RNA is not responsible for determining the nucleic acid sequence in mRNA. Instead, mRNA is transcribed from DNA and carries the genetic information encoded in the DNA sequence. D) All of these choices are correct: This statement is incorrect. The correct answer is specifically B) nucleotide sequence in DNA.

Final Answer

To summarize, the nucleotide sequence in DNA

(option b) determines the nucleic acid sequence in mRNA through the process of transcription. The mRNA molecule then carries this information to guide the synthesis of proteins during translation.
