What is the Relationship Between DNA and Chromatin

Question

What is the relationship between DNA and chromatin?
A) Chromatin is the collection of proteins encoded by DNA.
B) A chromatin is a DNA molecule that is separated during mitosis.
C) A chromatin is a unit of DNA whose sequence encodes a protein.
D) Chromatin is the combination of DNA packaged around proteins.

Accepted Answer

Chromatin is a combination of DNA packaged around proteins. The proteins involved in packaging DNA into chromatin include histones and non-histone proteins, which interact with the DNA to help regulate gene expression and protect the DNA from damage. While DNA and chromatin are related, they are not the same thing - DNA refers specifically to the genetic material that encodes the instructions for an organism's traits, while chromatin refers to the structure that DNA is packaged into within a cell.
