WebHow do base analogs lead to mutations? Base analogs have structures similar to the nucleotides and can be incorporated into the DNA in the course of replication. Many analogs tend to mispair, which can lead to mutations. DNA replication is required for the base-analog-induced mutations to be incorporated into the DNA. WebBase analogs are molecules which have a very similar structure to one of the four nitrogenous bases which are used in DNA ( adenine, guanine, cytosine or thymine ). They …
