Option D i.e. they are always linear DNA is not true concerning all bacterial plasmids.

Plasmids are crucial for bacterial evolution and adaptability to the environment because they contain genes that confer advantageous characteristics on the bacterial cell. Plasmids of many sorts can coexist in the same bacterial cell.

In every bacterial cell, plasmids are present by nature. All bacterial cells include plasmids, which are tiny, circular, double-stranded DNA molecules. These plasmids can independently reproduce because they are isolated from chromosomal DNA.

The plasmids contain genes for antibiotic resistance. Virulence Plasmids: The majority of the infection in the host body is caused by plasmids that contain viral genes. Degradative Plasmids: These plasmids include genes that cause the host genome to deteriorate.
