Genetic engineering 

vectors can be sued to insert DNA into other organisms 

idea is to move genes for desirable charcateristica from one organism to another. the organisms genome is chnaged in the process. 

a vector is something tahts used to transfer DNA into a cell.

plasmids are often used as vectors, they are small circular molcules of DNA that can be transferred between bacteria 

process

the DNA you want to insert is cut out with a restriction enzyme. restriction enzymes recognise specific sequences of DNA and cut out the DNA at these points 

the plasmid is then cut open using the same restriction enzyme 

this creates stciky ends on the DNA, short tails of unpaired bases that are complementray to each other

the plasmid and the…
