Question

Bacterial nucleoid has

• A. Single stranded DNA
• B. Double stranded DNA
• C. Single stranded RNA
• D. Double stranded RNA

Answer 1

The correct option is B Double stranded DNA

Bacteria is a prokaryote. It has nucleoid instead of proper nucleus. The nucleoid, is an irregularly shaped region within the cell of a prokaryote that contains all or most of the genetic material, called as genophore. In contrast to the nucleus, of a eukaryotic cell, it is not surrounded by a nuclear membrane. The genome of prokaryotic organisms, generally is a circular, double-stranded piece of DNA, of which multiple copies may exist at any time.
So, the correct answer is option B.
