Like other programmed gene rearrangements, however, gene amplification is a relatively infrequent event that occurs in highly specialized cell types; it is not a common mechanism of gene regulation. Gene amplification also occurs as an abnormal event in cancer cells, where it results in the increased expression of genes that contribute to uncontrolled cell growth.

The DNA rearrangements are caused by a set of mechanisms that are collectively called genetic recombination. Two broad classes are commonly recognized—general recombination and site-specific recombination. In this part of the chapter we discuss the first of these two mechanisms; in the next part, we consider the second mechanism.

Gene rearrangements refer to the process by which a cell's DNA sequence is altered through the reorganization of genetic material, playing a crucial role in creating diverse proteins and antibodies essential for immune system function. This biological mechanism involves the cutting and rejoining of DNA segments, often occurring in immune cells ...

Apr 17, 2012 · 2. Recombinations. Genetic recombination is a process that is catalyzed by many different enzymes called as recombinases. It can take place in all living cells from bacteria to eukaryota as well as viral genomes. This process mainly results in DNA repair, genomic rearrangements, variations and evolutional forces.
