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.

When in the replication process is DNA most vulnerable to mutations?

DNA is most vulnerable to mutations during the replication process, specifically during the DNA synthesis stage when mistakes can be made by the DNA polymerase enzyme. Mutations can also occur during exposure to external factors such as radiation or chemicals that can damage the DNA.


Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?

Interphase


How does polymerase prevent mutations?

It checks DNA for errors during replication.


How does DNA semi-conservative replication help prevent mutations in DNA replication?

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.


What could happen if DNA polymerase matches the wrong DNA bases during replication?

If DNA polymerase matches the wrong DNA bases during replication, it can lead to mutations in the new DNA strand. Mutations can cause genetic disorders, diseases, or changes in an organism's traits.


The substitution of one base for another during DNA replication is an example of what?

Mutations


Errors that are made during DNA replication may result in what?

Mutations


What are the changes in the genetic code called that can during DNA replication?

Mutation


Is it common for mistakes to occur during DNA replication?

Yes, it is common for mistakes to occur during DNA replication. These mistakes are known as mutations and can lead to genetic variations.

What can cause changes in DNA sequences?

mutations


Can Mutations can spontaneously occur during DNA replication?

Yes, mutations can spontaneously occur during DNA replication due to errors in DNA polymerase, exposure to mutagens, or other factors that can introduce changes in the DNA sequence. These mutations can result in changes to an individual's genetic material, which may lead to genetic disorders, disease, or potentially even evolution.
