What are the chromatin composed of?
A
RNA
B
DNA
C
Phospholipid
D
Chromosome
Explanation: 

Detailed explanation-1: -Chromatin refers to a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms. Many of the proteins-namely, histones-package the massive amount of DNA in a genome into a highly compact form that can fit in the cell nucleus.

Detailed explanation-2: -The complexes between eukaryotic DNA and proteins are called chromatin, which typically contains about twice as much protein as DNA.

Detailed explanation-3: -Chromatin is composed of a cell’s DNA and associated proteins. Histone proteins and DNA are found in approximately equal mass in eukaryotic chromatin, and nonhistone proteins are also in great abundance.

Detailed explanation-4: -A complex made up of proteins and DNA (Deoxyribonucleic acid) that forms chromosomes is called chromatin. It contains histone and non histone proteins, DNA, and RNA (Ribonucleic acid) as well. RNA plays a crucial role in the structural organization of the chromosome.
