BOTANY

Detailed explanation-1: -A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms. Plasmids are physically separate from chromosomal DNA and replicate independently.

Detailed explanation-2: -1. Which of the following is true regarding taking up of plasmid DNA in the bacterial cells? Explanation: There are more chances of having a single plasmid in one cell.

Detailed explanation-3: -So, the correct option is ‘Plasmids do not depend on host enzymatic machinery for their replication’

Detailed explanation-4: -Plasmids are extra-chromosomal small circular DNAs that are capable of replicating independently of the host, and are present throughout a variety of different microorganisms, most notably bacteria.

Detailed explanation-5: -Bacteria have a single circular chromosome that is located in the cytoplasm in a structure called the nucleoid. Bacteria also contain smaller circular DNA molecules called plasmids.
