how does the structure of DNA determine the structure of RNA?

A- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases cytosine in DNA and uracil in RNA will pair together when DNA acts as a template for constructing RNA.

B- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases uracil in DNA and guanine in RNA will pair together when DNA acts as a template for constructing RNA.

C- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases adenine in DNA and thymine in RNA will pair together when DNA acts as a template for constructing RNA

D- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA

Respuesta :

B is the correct answer

The nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).

  • During transcription, a sequence of DNA is used as template to create an RNA, usually an mRNA.

  • In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Guanine, Thymine, Cytosine and Adenine.

  • According to the base pair rules, Adenine pairs with Thymine (Uracil in RNA), whereas Guanine pairs with Cytosine.

In conclusion, the nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).
