12.6 DNA Repair
... Photoreactivation repair uses light energy to split pyrimidine dimers that kink the DNA. Pyrimidine dimers - bonds between C’s and/or T’s on the same strand. Photolyases - enzymes that absorb light energy and use it to detect and bind to pyrimidine dimers, then break the extra bond. Humans do no ...

The genome may be subdivided into chromosomes, each of which is a very long single continuous DNA molecule. In ...
