Chromatin is composed of chromosomes
Webhomologous chromosomes -maternal and paternal pairs -in humans their are 23 pairs of these -numbered in kyrotype sister chromatids -attached to each other by cohesion -replica of single chromosome -formed during interphase -separated during mitosis WebChromosomes are structures that look like thread, which live in the nucleus (center) of cells. One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus. Without these, our chromosomes would be as tall as we are!
