What are the main differences between polymerase activity and exonuclease activity?
I'm curious about the differences between polymerase activity and exonuclease activity. Can you explain it to me?
Sure! Polymerase activity is responsible for adding nucleotides to a growing DNA strand during DNA replication or repair, while exonuclease activity is responsible for removing nucleotides from a DNA strand. Essentially, polymerase activity builds the strand, while exonuclease activity repairs or modifies it.
