Vedclass · Answer

(B) plasmid is an extrachromosomal,circular,double-stranded $DNA$ molecule found in many bacteria.It possesses the ability to replicate autonomously within the bacterial cell,independent of the chromosomal $DNA$ replication control.While plasmids often carry genes that provide advantages (like antibiotic resistance),they do not contain genes essential for the basic vital activities of the cell,which are located on the main chromosomal $DNA$.
