What type of mutation does Depurination result in?

• Frameshift mutation

• Substitution mutation

• Addition mutation

If a whole section of DNA is removed including the mismatch, it is part of:

• Depurination

• DNA Mismatch Repair

• DNA Damage Repair

• Deamination

During DNA Damage Repair, this process takes place:

• incision

• excision

• photosynthesis

• substitution

Which enzyme cuts the damaged nucleotide during DNA Damage Repair?

• Histone

• Ligase

• Primase

• Nuclease

Okazaki fragments allow for DNA synthesis on which strand?

• Leading Strand

• Lagging Strand

Which group of enzymes removes the mismatched section of DNA during DNA Mismatch Repair?

• Nuclease

• DNA Mismatch Repairing Proteins

• DNA polymerase

• Ligase
