Why Heterochromatin Is Genetically Inactive?

by

Why Heterochromatin Is Genetically Inactive? The two types of chromatin, heterochromatin and euchromatin, are functionally and structurally distinct regions of the genome. Heterochromatin is densely packed and inaccessible to transcription factors so it is rendered transcriptionally silent (Richards and Elgin 2002). Is heterochromatin genetically inactive? Heterochromatin mainly consists of genetically inactive satellite sequences, and many

How Are Chromatin Packaged Chromosomes?

How Are Chromatin Packaged Chromosomes? These proteins are called histones, and the resulting DNA-protein complex is called chromatin. … Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. What is chromatin packing? Chromatin is the material that
