It is humans instinct to want to have and create the best of everything. With this drive and scientific knowledge we are able to manipulate a species genetics through several methods. The two methods I will be exploring the process of and the pro’s and con’s is ‘selective breading’ and ‘transgenesis’.

TRANSGENESIS:
Transgenesis is a form of genetic manipulation where an exogenous gene is introduced into a living organism that is not of the same species as the exogenous gene. This gene will then also be present in the offspring of that organism. An example of this is within corn. The corn is genetically modified to produce its own ‘natural’ pesticide, this is known as ‘BT corn’. The problem with natural corn was that the silk worms liked to eat it. Scientists noticed a type of soil which the silk works would die in. From this they found the Bacillus thuringiensis bacteria which they were then able to undergo genetic manipulation of the corn and enhance it by adding this bacteria to its genetic make up, thus resulting in the will worms not eating the corn. There are five main steps in the process of crop genetic engineering.

The first step involved in transgenesis is DNA extraction. DNA (deoxyribonucleic acid) is “a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information”. This information codes for the production of all the proteins an organism will ever need. DNA or a…
