Transfer of some chromosomal material from one bacteria uses -

Ans. is 'a > c > b' i.e., F factor > Transfer factor > R factor The plasmid which is responsible for conjugation is called as transfer factor. The plasmid may be R-factor, which codes for transferrable multiple drug resistance. But, some plasmids have the ability to mobilize the chromosomal genes of bacteria it is called F-factor. The F-factor is a transfer factor which helps in conjugation.
