Chapter 7, Problem 3MC
Summary Introduction
Introduction:
The plasmid is an extra-chromosomal DNA present in a prokaryotic cell, which is separated from the chromosome and able to replicate independently. It also carries the gene, which provides the special feature to the prokaryotes such as kappa particle and antibiotic resistance.
