What Would Be the Consequence If One Base Were Changed

Question

What would be the consequence if one base were changed in the base sequence of a DNA molecule?
A) Messenger RNA would correct the mistake.
B) Genome copying would be impossible.
C) Protein synthesis would stop.
D) A defective protein could be produced.

Accepted Answer

If one base were changed in the base sequence of a DNA molecule, it could result in a different amino acid being incorporated into the protein during translation. This could potentially result in a defective protein being produced, which could affect normal cellular functions.
