Usages of Genetic Engineering

There are uses of genetic engineering that can benefit the society. Once again, I reiterate the definition of genetic engineering, which is the direct modification of the characteristics of an organism by manipulating its genetic material by using biotechnology.

Reasons for Genetic Engineering

Genetic engineering is the direct modification of the characteristics of an organism by manipulating its genetic material by using biotechnology. Obviously there are pros and cons for genetic engineering, but for this tutorial, I will state the pros.

Acids and Bases

In the pH scale, there are acids and bases from 0 to 14. The acids are from 0 to less than 7. The nases are from more than 7 to 14. However, there are even stronger acids and bases that goes below 0 and above 14. If you use a litmus paper, red represents the…
