One example of a GM organism is the salmon that grows quickly than the wild salmons. This was made possible when scientists inserted a gene that is responsible for the growth hormones.

Biotechnology created a way for scientists to know how a disease can be treated and prevented by developing transgenic technology and conducting genetic tests and medical researches.

One example of the development of transgenic technology is the production of golden rice. Unlike white rice, this type of rice contains essential vitamins like beta carotene that improve human health.

Gene therapy has been discovered using biotechnology. This allowed the scientists to explore the possibility of treating a disease by transforming the genes.

The term DNA fingerprinting refers to a molecular biology tool that allows the scientists to identify individuals using sections of their DNA. This is a helpful method that is used by law enforcers in their criminal investigations. In addition, this technique also helps people in establishing paternity.

Variation in the genes can affect cellular processes. In this case, genes may impact the response of a person to medicines or drugs. An example of this is when a person has a variant of gene CYP2D6, which processes morphine at a very fast rate. This gene makes a person have a fast metabolism, which results in unexpected or exaggerated reactions toward medicines.

Here are the questions which might help in making a decision regarding which company to use for DNA testing:

1. What are the types of DNA tests conducted by the company?
2. How is the DNA collected? Does it collect saliva or cheek swab sample?
3. How long does it take to get the results?
4. How long can the results be stored?
