*2.2.2 Transposons*

These are already known as jumping genes. These are short chains of DNA that jump from chromosome to plasmid or vice versa. DNA transfer can occur between bacterial chromosome, plasmids, and bacteriophages. The most salient feature of transposons is that DNA acquired is easily integrated into the host chromosome or plasmids. Unlike plasmids, jumping genes are not self-replicating, and they must be kept within a self-replicating structure to replicate them [19].
