Holliday model for homologous recombination. 1) First, DNA is nicked at the same site on two paired chromosomes. 2) Next partial unwinding of the DNA allows strand invasion. 3) Enzymatic ligation generates a crossed-strand intermediate (Holliday junction) 4) The cross-strand structure can move along the duplex.
Dec 30, 2022 · (A) rearrangement of α chain and (B) β chain (C) protein structure of TCR. The enzyme that produces this diversity is a complex called the V(D)J recombinase. The recombination occurs in two parts: first double-stranded breaks are made at re- combination signal sequence (RSS) sites, then the breaks are repaired by the general double-stranded break repair 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 ...
