DNA polymerase checks DNA for errors.
DNA polymerase checks DNA for errors by breaking the hydrogen bonds between the paired nitrogen bases in the DNA molecule. This causes the molecule to separate into two individual strands.
DNA polymerase backs up, removes the incorrect nucleotide, and replaces it with the correct one.
Just learned this! the key check points in the cell cycle, the cells won't divide and replicate until dna is ok.
There are various enzymes and other factors that are able to prevent or recognize errors in DNA replication and repair them. Refer to the related link below.

It checks DNA for errors during replication.
Yes
The failure of DNA replication during the cell cycle can cause mutations. If such mutations occurred in a person's DNA, the person can end up getting cancer.
Replication.
It is important that the DNA is copied exactly during replication because any errors in replication can cause mutations. For example, even one incorrect base can result in an enzyme becoming inactive. These mutations can be lethal or have severe consequences on the organism's health.
It checks DNA for errors during replication.
Yes
Interphase
Semi conservative replication prevents mutations during DNA replication because it produces 2 copies that each contained 1 of the original strands and 1 entirely new strand.
The failure of DNA replication during the cell cycle can cause mutations. If such mutations occurred in a person's DNA, the person can end up getting cancer.

Mutations
RNA polymerase doesn't have a proofreading function.
Interphase
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
