Chapter 20, Problem 12SQ
Summary Introduction
Introduction: Plasmids are the extra-chromosomal circular DNA found in many bacterial cells. Plasmids are used for the bacterial conjugation. It consists of genes like antibiotic resistance gene that provides the bacterial cells with additional features. Plasmids are independent of the chromosomal DNA for their replication. Plasmids are varied in size (ranges from hundreds to thousands of DNA base pairs per plasmids).
