Sir3 gene silencer acting on DNA,molecular model. Sir3 (purple and grey) is acting on a circular strand of DNA (deoxyribonucleic acid,red). Sir3 is an example of a silent information regulator (Sir) found in yeast such as Saccharomyces cerevisiae. Here,the DNA is wrapped around a histone core (blue and pink),forming a structure called a nucleosome. The region of the Sir3 gene silencer shown here is the BAH (bromo-associated homology) domain | |
