Question

Prokaryotic genetic system has

• A. Both DNA and histones
• B. DNA but no histones
• C. Neither DNA nor histones
• D. Either DNA or histones

Hint:

Prokaryotic DNA is naked and not organized with histone proteins.

Answer 1

The Correct Option is B

Step 1: Prokaryotic organisms possess genetic material in the form of DNA.
Step 2: Unlike eukaryotes, prokaryotes do not have true histone proteins associated with their DNA.
Step 3: Their DNA is present in a nucleoid region and is not enclosed by a nuclear membrane. Hence, the prokaryotic genetic system has DNA but no histones.
