We can use the technique of DNA technology to recombine and copy genes,a restriction enzyme is used to cut open a plasmid,a small circular DAN molecule obtained from a bacterium,the restriction enzyme cuts only a at certain DNA base sequence,the same enzyme is used to cut up a DNA obtained from a human cell.The restriction enzyme produces DNA fragments that have matching sticky ends that joined by complimentary base pairing.An enzyme called DNA ligase forges covalent bonds that join human and plasmid DNA,creating recombinant DNA,the human gene must be cloned to produce copies for use or study.A bacterium is induced to take up the recombinant plasmid from the surrounding solution in a process called transformation.A bacterium is placed on a growth medium,it replicates the plasmid at the same time as its own DNA,its descendent forms a clone of bacteria that all have copies of….
