Question

What is the difference between DNA and chromosome?

Answer 1

The difference between DNA and chromosomes is as follows:

1. A chromosome is a long chain of DNA molecules that contains part of all of the genetic material of an organism.
2. DNA is a fundamental molecule that carries the genetic instruction of all living organisms.
3. DNA is packed into chromosomes with the help of special proteins called histones.

DNA	Chromosome
DNA is the chemical form which stores genetic information.	The chromosome is the highest organized structure containing condensed DNA double helix along with histone proteins.
Made up of nucleotide monomers of four nitrogenous bases i.e. Guanine, Adenine, Cytosine, Thymine.	Made up of DNA and histone proteins in eukaryotes and DNA plus non-histone proteins in prokaryotes.
Identification is done via gel electrophoresis.	Identification is done via karyotyping or microscopy.
