She has written about science as it relates to eco-friendly practices, conservation and the environment for Green Matters.Patenting Genes: Pros and Cons Pros: * Gives companies that patent genes time to look at the genes without competition.
Will societal division swell between genetically modified people and "normal" people?
These are questions that scientists and the public will likely continue to consider as humanity moves toward a future where manipulating DNA is easier than ever before.
Animal insulin is not a suitable replacement, since it causes severe allergic reactions in most people.
Thus, scientists used recombinant DNA technology to isolate the gene for human insulin and insert it into plasmids (cellular structures that can replicate independently of chromosomes).
Fruits and vegetables, which were prone to attacks from pests, now have genetic modifications to be more resistant.
Some foods have modifications for longer shelf lives or higher nutritional content.
Recombinant DNA exists in a laboratory by combining genetic material from multiple sources.
Recombinant DNA technology can create new kinds of living organisms or alter the genetic code of existing organisms.
These "DNA vaccines," which utilize recombinant DNA, are in the testing stages.
Most modern vaccines introduce a small "piece" of a disease into the body, so the body can develop ways to fight that particular disease.
