What else can I help you with?
What cell cause mutations?
DNA polymerase
How does mutations occur during DNA replication and transcription?
During DNA replication, mutations can occur due to errors made by DNA polymerase when copying the DNA template. These errors can result in base substitutions, insertions, or deletions in the new DNA strand. During transcription, mutations can occur if RNA polymerase inserts the wrong nucleotide into the messenger RNA (mRNA) strand, leading to incorrect genetic information being transcribed from the DNA template.
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.
What happens to DNA polymerase if the protein is not present?
Without DNA polymerase, DNA replication cannot occur effectively, leading to incomplete or inaccurate copying of the DNA template. This can lead to mutations, genetic disorders, and cell death. The absence of DNA polymerase can disrupt the cell cycle and ultimately impair cell function and viability.
What chemical is an enzyme that add nucleotides to a new strand of DNA during replication?
DNA Polymerase is the enzyme which adds new nucleotides during replication.
What cell cause mutations?
DNA polymerase
How does polymerase prevent mutations?
It checks DNA for errors during replication.
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.

What chemical is an enzyme that add nucleotides to a new strand of DNA during replication?
DNA Polymerase is the enzyme which adds new nucleotides during replication.
How are mutations prevented during DNA replication?
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.
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
Repair of damaged DNA might be viewed as a race between an endonuclease and?
a DNA polymerase. The endonuclease recognizes and cleaves the damaged DNA, creating a site for repair. The DNA polymerase then fills in the gap with the correct nucleotides, restoring the integrity of the DNA molecule. This race determines whether the DNA is successfully repaired or if mutations will persist in the repaired sequence.
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.
Is DNA polymerase a protein?
Yes, DNA polymerase is a protein.
