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.
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, ...
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 ...
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, ...
The genetic-testing company, which collected DNA data from users, is for sale in bankruptcy court. Now, 27 states and the District of Columbia oppose selling the data without express consent.

If histone modification, DNA spooling, and gene expression are altered due to environmental influences, such as chronic cocaine exposure, behaviors may change, including behaviors such as cocaine ...
While we have yet to explore the state of DNA modifications on oxygen-deprived squid, our study of squid histones shows that histones are modified to promote DNA condensation (or spooling), making ...
Usually, DNA is organized into chromosomes, each a long string of millions of chemical units, or base pairs, of genetic information. But in most of the frozen mammoth cells, the DNA had crumbled ...
