Recbcd chi
WebbOligonucleotides with the Chi sequence at one end, or the Chi sequence alone in an 8mer, failed to show Chi-specific inhibition of RecBCD. Thus, Chi recognition requires that Chi be flanked by DNA at either end. Further experiments indicated that the oligonucleotides inhibit RecBCD from binding to its dsDNA substrate. Webb29 maj 2016 · homologus recombination 1. 1 Presented By Deepak PI-292 NIPER (Hajipur) 2. Introduction Homologous recombination is a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. It is most widely used by cells to accurately repair harmful breaks that occur on both …
