Now a second question we wanted to answer was how is it that chromatin opening and closing is controlled?

- Alcohol also impacts chromatin, the genetic material comprising our chromosomes and non coding RNAs in sperm.
- First of all, it is more like the long term mechanism, whereas the chromatin structure can change very quickly and the micrornas can too.
- Is it, does it involve like external chromatin looping or is it just like kind of a local interaction right at the binding site?
Examples
-
The transition from PSCs to erythroid progenitor cell lines is associated with extensive chromatin remodeling that ensures activation of erythroid-specific genes.

And so in a simple way is how does a single letter change in the genome affect chromatin and gene regulation?

-
OK, So DNA methylation causes the chromatin to be a bit more compact and more stable.
-
Today, techniques are available to analyze the remodeling of chromatin proteins directly.
Academic text (1999) -
Methylation leads to changes in local chromatin configuration that, in turn, alter the accessibility of genes to regulatory proteins.
Academic text (1993) -
Several studies have examined the specific DNA and chromatin features associated with promoters of genes with Pol II pausing.
Academic text (2018) -
During cell division, chromatin condenses to form visible chromosomes that carry genetic information.
-
In the nucleus, chromatin plays a crucial role in packaging DNA and regulating gene expression.

Etymology
Chromatin comes from the Greek root chroma 'color' and the ending -in for a substance. A helpful way to remember it is that chromatin is the 'colored' material in the cell nucleus that takes dye and then forms chromosomes during cell division.
