Question: Which process ensures the accuracy of DNA replication?

Options:

Correct Answer: Proofreading

Solution:

Proofreading by DNA polymerase ensures the accuracy of DNA replication by correcting errors.

Which process ensures the accuracy of DNA replication?

Which process ensures the accuracy of DNA replication?

Step 1: DNA replication is the process where DNA makes a copy of itself.
Step 2: During replication, DNA polymerase is an enzyme that adds new DNA bases to the growing strand.
Step 3: Sometimes, DNA polymerase might add the wrong base by mistake.
Step 4: To fix these mistakes, DNA polymerase has a proofreading ability.
Step 5: If DNA polymerase detects an error, it removes the incorrect base.
Step 6: After removing the wrong base, DNA polymerase adds the correct base.
Step 7: This proofreading process helps ensure that the new DNA strand is accurate.
