Which of the following is true regarding plasmid
|A||They may confer drug resistance|
|B||They may code for capsular synthesis|
|C||They are extra chromosomal genetic elements|
|D||All are true|
a. Plasmids are extra chromosomal genetic elements, which can replicate on their own. The plasmids, which can transmit itself from one bacterium to another by formation of sex pilus or conjugation tube is known as F plasmid.
b. While F plasmid, which can transfer antibiotic resistance, is known as R plasmid. Plasmids can encode for virulence factors like exotoxins and capsules. Bacteriophages can also transmit them by transduction.
