DNA strands wrap around histones, which are clustered into eight-histone balls that are threaded like beads on a string into fibers that are further intertwined to form chromosomes. Cells don’t store ...
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 ...
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 ...
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 ...
