Genetics Essay Research Paper Over the past (стр. 2 из 2)

as well. They have been able to genetically modify plants to help them survive longer and

produce better food, flowers, or fragrance depending on what they want enhanced.

Genetically Modified foods have become more common in recent years. It was mostly

grains that have been engineered with genes from non-grain species that make the plants

resist insects or tolerate pesticides. So a farmer can spray his crops with a pesticide and

have it kill everything in its field except his harvest. There are some problems with this,

such as allergies in humans. Scientists have yet to figure out whether or not people can

develop allergies towards GMOs, but some people don t want to take the chance. The

pesticide resistant plants could jump to wild plants, creating super-weeds or could harm

valuable insects by making their food unfit to eat, such as the Monarch butterfly. The

Genetically Modified Atlantic and Pacific salmon are growing faster than normal salmon, if

the super-salmon were to escape from the production plantations, they could mate with

normal salmon and corrupt their whole genetic pool. There is also problems with patent

genetically modified plants, if a person suspects that his neighbor was stealing his

super-seeds, the only way to prove he s not is to spray his field. If the crop dies then he is

not stealing the crops, but he lost all that years harvest. If the crop lives, then the company

can sue the neighbor. So you can see that there is a number of problems that could arise

with releasing the GMOs. Some Health officials don t agree with Genetically Modified

foods, claiming that it is unhealthy and dangerous to humans and the environment, if not

properly controlled. Right now in Canada they are looking for better ways to control

GMOs and the sale of them. Officials believe that their will be a lot of problems with

GMOs and how people will react to them being on the shelf, they think that there will be

destruction of fields and food products just like the reaction in Europe last year.

(Articles #21,22,24)

After figuring out the genome of humans there is still Protenome, a complete

listing of the 250,000 or so proteins that the 35,000 genes are capable of making. Proteins

can vary in health and disease, and the long chains of amino acids do not string out but

curl up on themselves in complex 3D shapes, making it indefinitely harder to break the

code. Most of biology happens at the protein level, not the DNA level, Dr. Craig Venter

of Celera Genomics points out. Scientists not only have to figure out what the listing of

proteins is but how they change in disease and how they fold. This is dubbed the Greatest

unsolved problem in biology. (Article #27)

As you can see there is still a long way to go in finding out everything there is to

know about Genetics. But when we do find out everything about Genetics and the human

body, there is nothing left to the imagination, and a part of that will be sorely missed.
