What happens in the following types of point mutation?
Gene conversion 1. An error occurs in DNA replication and the wrong base is inserted into the new DNA e.g. rather than thymine (which pairs with adenine), cytosine (which pairs with guanine) is added instead. 2. Most DNA polymerases have a proof reading ability and when the fault is reached and the adenine-cytosine pair is discovered, the DNA polymerase replaces withe original adenine with guanine (rather than repairing the error correctly) and so the original AT pair is then replaced in the new molecule with a CG pair. Translocation Is simply the movement of a segment of chromosome from one place to another. They can either be reciprocal, when two pieces swap place, or non-reciprocal when one piece moves to a new location. They can have quite drastic effects. Robertsonian translocation is the most famous types and can easily be searched on the web.
