Chromatin is the complex of DNA and protein found inside the nuclei of eukaryotic cells. The nucleic acids are in the form of double-stranded DNA (a double helix). The major proteins involved in chromatin are histone proteins, although many other chromosomal proteins have prominent roles too.

The functions of chromatin are to package DNA into a smaller volume to fit in the cell, to strengthen the DNA to allow mitosis and meiosis, and to serve as a mechanism to control expression.

Chromatin is that portion of the cell nucleus which contains all of the DNA of the nucleus in animal or plant cells. (A small amount of special DNA is also found in the mitochondria of the cell cytoplasm outside of the cell nucleus.)

Chromatin is made of the strings of DNA in a cell. The DNA is in this form except during mitosis or meiosis when the chromatin coils up to make chromosomes.

Chromatin has the DNA that tells how to make the proteins for the cell.

Plant and animal cells both have chromatin.

Chromatin is inside the nucleus of a cell.

Chromatin is composed of DNA (deoxyribonucleic acid) and a protein called histone. During cell division it curls up and is referred to as chromosomes (perhaps you're more familiar with that word since it's used more frequently) anyway, the only difference between chromatin and chromosomes are they physical structure. The funtion of the chromatin is to contain the DNA, which you need to produce proteins that define the traits that make you you. It's located in both plant and animal cells in the nucleus. Can't really think of anything else off the top of my head, if you have any further questions please email me.
