The pairing of homologous chromosomes at synapsis leads to increases in genetic variability in, for 10 points, what genetic process where parts of DNA or RNA strands are exchanged between molecules?
A subdivision of this process involves activation-induced deaminases and results in exclusion of mu and sigma type amino acid chains. That subprocess, known as isotype switching, involves the Fc region of an antibody's heavy chain. The dimeric Ku protein is involved in a type of this process that uses short single-stranded overhangs of DNA. In fungi, gene conversion refers to a rapid occurrence of this process during meiosis and leads to variant copies of the initial genome. This process is used in laboratories to generate knockout organisms or plasmids, and natural occurrences of this coincide with the appearance of Holliday junctions.
