Scientist have expanded the shell life of tomatoes by inserting a gene into its DNA. There are also other crops that have been modified to resist pest without the use of harmful pesticides. Pesticides can unintentionally alter the balance of the ecosystem by killing various of species or contaminating clean water. However, there is a growing opposition to genetically modified organisms on the basis of health. Scientist can make multiple copies of DNA through a process called gene cloning. First, the DNA of interest is inserted a plasmid, forming recombinant DNA. This is then inserted into bacteria who divide into offspring with the recombinant DNA. Now, scientist have many copies of the DNA which can be extracted and purified. In fact, this is how insulin is made which is useful in a country where obesity is a major problem. Other medications can be obtain using this technique. The pathway of protein can be tracked by the gene that makes jellyfish glow, giving scientist insights on how it works. This can be especially useful in underlining the root cause of certain
