Question

Bacterial plasmids are
A. Circular dsRNA
B. Circular dsDNA
C. Linear dsDNA
D. Linear dsRNA

Answer 1

Hint:It is found in the bacterial plasmid as genetic material and very rarely present in eukaryotic organisms and archaea.

Complete answer:
Plasmid is a short, extra chromosome DNA molecule inside a cell that is physically isolated from chromosome DNA and can be repeated independently. Plasmids have a lot of different functions. They can contain genes that improve the longevity of the organism, either by destroying other organisms or by protecting the host cell by creating toxins. Any plasmids promote the replication mechanism in bacteria.
Bacterial plasmids are mostly located as small spherical, double-stranded DNA molecules in bacteria, but occasionally plasmids are found in eukaryotic species and archaea. In nature, plasmids also bear genes that favor the survival of the organism and confer evolutionary advantages such as antibiotic resistance. While chromosomes are wide and include all the necessary genetic material for living under normal circumstances, plasmids are typically very small and include only additional genes that may be useful in specific cases or diseases. Artificial plasmids are commonly used as vectors for molecular cloning, which is used to push replication of recombinant DNA sequences within host species.

Thus, the correct answer is option” B”. i.e., Circular dsDNA.

Note:Plasmids are regarded replicons, DNA units capable of self-replicating within an adequate host. However, plasmids, such as viruses, are not commonly known as life. Plasmids are transferred from one bacterium to another mainly through conjugation.
