lentify the various types of DNA repair mechanisms known to counteract the effects of UV Padlatloh. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Reset Help sos repair is dependent on a photon-activated enzyme that cleaves thymine dimers. excision repair is the process by which an endonuclease clips out UV-induced dimers, DNA photoreactivation repair polymerase IIl fills in the gap, and DNA ligase rejoins the phosphodiester backbone. recombinational repair uses the corresponding region on the umdamaged parental strand of the same polarity. is a process in E. coli that induces error-prone DNA replication in an effort to fill gaps by inserting random nucleotides.
