Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error ...
What are the consequences of having pyrimidine dimers in DNA? 1. They form an extra phosphodiester bond between them. 2. They create an apyrimidinic site. 3. These dimers distort the DNA structure and What happens to most of the enzymes responsible for DNA synthesis around the repli...
