Question

The extra chromosomal genetic material seen in a bacterial cell capable of replication is called as

• A. Plasmid
• B. Mesome
• C. Nucleoid
• D. Chromatin

Answer 1

The correct option is A Plasmid

A plasmid is an extra-chromosomal element, often a circular DNA. The plasmids have three important elements i.e., an origin of replication, a selectable marker gene, and a cloning site. They are most commonly found in bacteria as small, circular, double-stranded DNA molecules and having the capability of autonomous replication within the host cell.

So, the correct answer is option A.
