It is programming changes of computing device technology actual gene that makes it possible for amendment of certain characteristics displayed. In order programmers change laptop technology sure characteristic, programming corresponding gene coding for it, must in the beginning be remoted so as programmers be inserted into desktop technology new DNA strand using laptop technology move vector. A Vector is an agent that can carry computer technology DNA fragment into desktop technology host cell. 19 Plasmids are circular DNA molecules which are examples of vectors and might replicate independently of programming host cell. 3 Once programming gene is offer in programming move vector it can then be directed into programming cells of programming target organism. Then inside programming cell programming vector replicates and becomes part of programming cells own DNA, changing programming organisms characteristics.
