What is true about genetic material of a prokaryotic cell?

A

Lacks histones

B

Not enveloped by nuclear membrane

C

Composed of a single circular DNA molecule

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
In prokaryotes, the genetic material consists of single circular DNA molecule lying entangled in nucleoid. It is not bounded by a definite nuclear membrane. Histones are water-soluble proteins rich in arginine and lysine that help in DNA packaging in chromosomes. Prokaryotic cells lack histone proteins.
