.... in living organisms. Some of these enzymes can cut and join strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell and insert themselves into its DNA. Scientists started to build vectors, which incorporated genes of their choosing and used vectors to insert these genes into the DNA of living organisms. Genetic engineers believe that they can improve the foods we eat by doing this. At first glance, this might look exciting to some people. Deeper consideration reveals some advantages ....
