At which point in the eukaryotic cell cycle can a dna mutation occur? g1 phase g2 phase s phase m phase

During the S phase where DNA is replicated, mutations can then occur.

The correct answer will be option- S phase.

Explanation:

The mutation is the alteration or change in the nucleotide sequence of the genetic material- DNA of the organisms. This mutation if passed on to the generations can lead to the formation of new genotype and phenotype which could be beneficial or harmful to the organism.

The mutation in the DNA usually takes place in the "S-phase or synthesis phase" of the cell cycle which is marked by the replication stage of the DNA. The mutation could be due to the addition, deletion or substitution of the sequence which could pass on to the generations.

Thus, the option- S phase is the correct answer.
