Question

Dna exists in a double-stranded form whereas rna is mainly a single-stranded molecule. what is the likely reason for dna being double-stranded?

a. it is easier to replicate double-stranded dna
b. rna strands cannot form base pairs
c. double-stranded dna is a more stable structure
d. dna cannot exist in the single-stranded form

Answer 1

The likely reason for DNA being double-stranded is because it is a more stable structure.

Step-by-step explanation:

The likely reason for DNA being double-stranded is because double-stranded DNA is a more stable structure. The two strands of DNA are held together by hydrogen bonds between complementary base pairs. This stability allows for accurate replication and protection of genetic information.
