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. WebThere are different types of genetic mutations that can occur in a cell. Point mutations involve the replacement of one base with another.Frame-shift mutations occur when a base is added or removed from the sequence. WebBase analogs, like 5-bromouracil, which we also call 5-BU, pretend to be a certain base, but then act differently than that base normally would.
