Answer 1

The complex of DNA and protein that makes up a eukaryotic chromosome is properly called chromatin.

What is the structure and function of chromatin?

• Eukaryotic cells nuclei include a combination of macromolecules called chromatin, which is made up of DNA, RNA, and protein.

• Heterochromatin (condensed) and euchromatin are the two types of chromatin (extended).

• The main proteins that make up chromatin are termed histones, which act as bases for the DNA to wrap around to form the "bead-like" structures known as nucleosomes.

• A nucleosome is made up of 147 base pairs of DNA wrapped around an octomer, which is a collection of 8 histones.

• The chromatin fibre can be created by further folding the nucleosome.

• To create chromosomes, chromatin fibres are coiling and condensing.

• Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.
