The packaging of DNA in the cell nucleus is extremely well studied: Each DNA spool consists of two molecules each of four different histone proteins. In each nucleosome, ...

Accessing DNA wrapped into basic units of packaging ... This past experiment measured quite accurately the relative accessibility of different parts of the DNA spool for enzymes that cut that DNA.

In the cell nucleus, DNA wraps around what are called histone proteins, forming regularly spaced spherical bodies called nucleosomes. Thus, large portions of the genetic material are inaccessible ...

Chromosomes are packaging masters, without them DNA would simply not fit inside cells. Chromosomes keep DNA coiled around spool-like proteins known as histones, ...

Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer. Each histone octamer is composed of two copies each of the histone ...

The researchers discovered that such treatment also caused methyl groups to stick to histones (the DNA-spooling proteins) in the hippocampus. This action suppressed a gene that, ...

Stretched out, the DNA from all the cells in our body would reach Pluto. So how does each tiny cell pack a two-meter length of DNA into its nucleus, which is just one-thousandth of a millimeter across ...

Accessing DNA wrapped into basic units of packaging ... This past experiment measured quite accurately the relative accessibility of different parts of the DNA spool for enzymes that cut that DNA.
