Zoology - Biotechnology - Principles and Processes Question with Solution | TestHub

Vectors are carriers of$\text{DNA}$which are used to transfer gene of interest into the host cell. Vectors used at present are engineered in such a way that they help in easy linking of foreign DNA and selection of recombinants and non-recombinants. Plasmids and bacteriophages have the ability to replicate within the bacterial cells independent of the control of chromosomal$\text{DNA}$.
