Once a mutation is produced in a single strand of dna, that mutation wll become a permanent part of double stranded dna in the future.
a. true
b. false

True

Explanation: Mutation is the change process which occurs in the DNA strand pattern due to reasons like when the DNA is being copied and any incorrect factor affect the pattern of DNA like UV light , etc. When the DNA is mutated , it also becomes the part of the double stranded DNA . Thus the mutation will also reflect in the double stranded DNA and thus the statement given is true.

carbon atoms, hydrogen, oxygen, and nitrogen.
