Question

Match the statements with the correct types of DNA repair systems. Not all statements will be used Nucleotide excision Direct Mismatch DNA is scanned for the removal and replacement of a few incorrect base pairs Adenine binds to cytosine in a newly synthesized DNA strand Alkyltransferase removes methylated guanine. Enzyme complexes remove misplaced bases in the absence of DNA glycosylase, creating an apyrimidinic site in DNA. The methylation of guanine is corrected prior to DNA replication. The emergency repair systenm initiated when DNA damage is extreme Incorrect. Whereas other statements may also be misplaced, you have specifically misplaced the statement regarding the removal of a few incorrect base pairs. The UvrA and UvrB complex detects abnormalities in complementary base pairing. Which repair system uses complexes instead of single enzymes for repair? atch the statements with the correct types of DNA repair systems. Not all statements will be used.

The emergency repair system initiated when DNA damage is extreme Incorrect You have placed a statement that should remain unplaced. This emergency response occurs after nucleotide excision, direct, and mismatch repair systems do not correct the damage

Answer 1

Nucleotide excision repair is the repair mechanism that uses complexes instead of single enzymes for repair. It removes damaged bases caused by UV exposure.

Step-by-step explanation:

The repair mechanism that uses complexes instead of single enzymes for repair is the nucleotide excision repair system. Nucleotide excision repair is used to remove damaged bases, such as those caused by UV exposure. Enzymes called excision nucleases recognize the damaged bases, make a cut on both ends of the damage, and remove the segment of DNA. The DNA polymerase then fills in the gap with the correct nucleotides, and DNA ligase seals the gap.
