Answer 2

Plasmids are extra-chromosomal DNA, which can self-replicate. (option b)

• Plasmids are circular structures of double stranded DNA found in the cytoplasm of unicellular organisms like bacteria. They are not associated with the genome.
• Plasmids are very useful in the field of biotechnology. These structures are used as vectors to introduce a desired gene into a host organism.
• In most bacteria, these plasmids carry advantageous genes like those for antibiotic resistance. They are also transferred to other bacterial cells by recombination methods like conjugation.
