Difference Between Chromatin and Chromosomes

Chromatin:

It is a structure present in DNA double helix of eukaryotes. It consists of RNA, DNA and protein. It helps in easy package into the cell nucleus, DNA replication and in the regulation of gene expression. They are composed of nucleosomes and appear throughout the cell cycle. Condensation is 50 times more than DNA double helix. The structure of Chromatin is thin, long and uncoiled fibres. It is unwound DNA. DNA is used for macromolecule synthesis.

Chromosomes:

It is the highest condensed structure of DNA double helix along with protein. They are composed of chromatin fibres and appear during cell division i.e, metaphase and anaphase. Condensation is 10,000 times more than DNA double helix. The structure of chromatin is ribbon like, thick and compact. Tightly packed DNA. DNA is not used for macromolecule synthesis. There are four types of chromosomes. They are differentiated based on the centromere position. They are telocentric, acrocentric, submetacentric, metacentric.

To make you understand how chromatin and chromosomes are different from each other, here are the some of the major differences between chromatin and chromosomes:
