Question

1. what is the major structural difference between dna and rna? rna is double stranded, while dna is triple stranded. dna is double stranded, while rna is single stranded. rna is triple stranded, while dna is double stranded. dna is single stranded, while rna is double stranded.

Explanation:

DNA is typically double - stranded, consisting of two complementary strands held together by hydrogen bonds. RNA, in most cases, is single - stranded, although it can form secondary and tertiary structures through base - pairing within the single strand.

Answer:

DNA is double stranded, while RNA is single stranded.
