5.Molecular Basis of Inheritance
medium
$DNA$ 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
$RNA$ strands cannot form base pairs.
B
Double stranded $DNA$ is a more stable structure.
C
$DNA$ cannot exist in the single stranded form.
D
It is easier to replicate double stranded $DNA$ than single stranded $RNA.$
Solution
Double stranded $DNA$ is much more stable than single stranded $RNA$ and this helps to protect our genetic code. Having a second copy of our genetic code means that there is a reference for repair in the event of a mutation or damage.
