Due to many people in Periods 2/3 not understanding the questions / reading, this is due on TUESDAY.

GENETIC ENGINEERING

The practice of manipulating genes in DNA for practical purposes

Some common uses include:

Preventing bugs from attacking some types of plants

Slow bruising of apples and pears

BENEFITS OF GENETIC ENGINEERING

Genetic engineering can prevent use of some popular hormones that are used to fatten up pigs, and produce more milk in cows. Due to the inherent risk of using such hormones, genetic modification seems to be the simplest and the healthiest option.

ISSUES WITH GENETIC ENGINEERING

In some cases, genes from completely unrelated species are introduced to others. For example,a common gene in Arctic fish is used to prevent freezing in some tomatoes. This gene is widely used, and has not caused any major problems to date, but it has been blamed for possibly raising the risk of some diseases.
