Illustration of H2B or H3 tail-less nucleosomes. Nucleosomes lacking H2B and H3 tails exhibit weakened interactions between histone tails and nucleosomal DNA, leading to less stable nucleosome ...
A startling discovery in bacteria suggests that some species have a bizarre way of packaging chromosomes and regulating gene expression — using proteins that, until recently, weren’t thought to exist ...
Strands of DNA wrapped around a histone. Credit: Molekuul/Science Source Histones are among the most abundant proteins in the body. They act as spools that help compact DNA so our enormous genomes ...
