Which of the Following is False Regarding Plasmids

Question

Which of the following is false regarding plasmids?
A) They can have genes that promote their own transfer from one bacterium to another.
B) They contain essential genes for metabolism.
C) They can carry genes for antibiotic resistance.
D) They generally replicate autonomously.
E) They are small double stranded circular DNA molecules.

Accepted Answer

Plasmids are typically extrachromosomal DNA within bacteria that are not essential for basic metabolism but can provide additional functions such as antibiotic resistance. Essential genes for metabolism are usually found on the bacterial chromosome, not on plasmids.
