Chromosomes are thread-like structures in organisms, found primarily in the nucleus of the cell. These chromosomes contain genetic information and are involved in cell replication and reproduction. Along with DNA, chromosomes contain histones, which are proteins that keep the chromosome bound together.
<h3>Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.</h3>
