In bacteria, plasmid is : -
A
Extra chromosomal material
B
Main DNA
C
Non functional DNA
D
Repetitive gene
Detailed Solution
Plasmids are small, circular, double-stranded DNA molecules present in bacteria in addition to the main bacterial chromosome.
They replicate independently of the chromosome, so they are called extrachromosomal DNA.
They are functional: they carry genes for antibiotic resistance, fertility (F factor) and other properties, and they are used as vectors in genetic engineering.
So a plasmid is extra chromosomal material.
