Which of the following is most likely to create genetic variation in a population?

a
RNA polymerase errors during transcription
b
Helicase failure to unwind DNA during replication
c
DNA polymerase errors during replication
d
Misincorporation of amnio acids by tRNA during translation

Genetic variation is defined as the change in the genetic sequence of an organism of species. The genetic variation can be due to natural selection or mutation.

The correct answer is:

Option C. DNA polymerase errors during replication

Genetic variation can be caused by mutation. The mutation is the alteration of a genetic sequence, by inserting or deleting the nucleotide. The mutation can lead to the entry of a new allele in a population.

The chances of genetic variation in a population are most likely due to errors made by DNA polymerase during replication.

DNA replication is an essential process in which genetic material from the parent is transmitted to the daughter cell. However, the mutation or errors caused during the replication will lead to genetic variation.

Therefore, Option C is correct.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
