Question

gene mutation occurs at the time of
1. DNA replication 2. RNA transcription
3. DNA REPAIR 4. CELL DIVISION

Answer 1

Gene mutation occurs at the time of DNA replication.

DNA replication is a biological phenomenon. Most DNA replicates with high fidelity, and with polymerase enzymes.

Ans this leads to the inserting of wrong nucleotide into a sequence.

But however, these blunders are fixed through various DNA repair processes.

Answer 2

The correct option is 1. DNA replication

Gene mutation occurs at the time of 1. DNA replication

DNA replication is a biologically occurring phenomenon. With polymerase enzymes, most DNA replicates with high fidelity.

An improper nucleotide gets inserted into a sequence as a result of this.

However, these errors are corrected by a variety of DNA repair processes.
