What is the role of DNA in biotechnology?

One main use of biotechnology is genetic engineering. DNA plays a gigantic role in this process. Genetic engineering is the manipulation of the organism's genome. A new DNA must be inserted into the host genome, so you will need to make a copy of the original genetic material. Without the role of the DNA none of the biotechnology involved in genetic engineering would be possible.

How is biotechnology used in DNA testing?

DNA and biotechnology come together quite often to create all sorts of new helpful inventions. For example, DNA fingerprinting is when the specific, unique pattern of someones finger print can be traced to their DNA. If this persons DNA fingerprint was part of a crime than this biotechnology can help figure out the case.

Here is a picture of DNA finger printing:

How does biotechnology help in the medical industry?

Biotechnology has produced many human hormones like insulin. In 1929 the discovery of penicillin and the advent of biologically produced antibiotics was uncovered by a man named Alexander Fleming. He had observed that when growths from Staphylococcus aureus were contaminated with the fungus Penicillium notatum, they were killed.

How biotechnology is used in Agriculture?

Before 1971, biotechnology was primarily used and known for helping in the food processing and agriculture industry. Because biotechnology is used in agriculture many new plant varieties are being developed and grown right know. This is done by manipulating the plants genes (genetic engineering) and through modern molecular biology, also known as biotechnology.

How biotechnology is used to help in an environmental clean-up?

Biotechnology is a great help when a environmental "clean-up" is needed. Take an oil spill for example, Biotechnology is what made cleaning up the oil possible. We have created genetically engineered microorganisms that grow rapidly in oil, so they will suck up the water that has been contaminated with oil and let the genetically engineered microbes do their job of breaking the oil into non-toxic materials.

One possible career involving biotechnology.


The basic responsibilities of this job is that they must plan and facilitate trials of the drug testing, enrolling volunteers in clinical trials, documenting the findings from the trials, following ALL guidelines and administrations, and finally they must record the data and present final project proposals to their sponsors. Now there are many more requirements that go more into depth and detail, for instance what exactly they must do during an investigation, and how to figure out the correct dosage levels, the potential side effects from the medicine they would be testing, and all of the protocols necessary for a beneficial medicine. All of these things you would learn in the medical-related education from an accredited program necessary for this job.

North Carolina's rank in biotechnology:

North Carolina has a reputation as home to a significant and growing biotechnology industry. According to the web site North Carolina in the Global Economy, "In 2005, more than 1,400 biotechnology companies existed in the united states with North Carolina being home to just under 6% (81) of these biotechnology firms. The state is ranked among the five largest biotechnology industry centers in North America..."

What are some potential negative impacts of biotechnology?

  • Scientists have recognized that insect will form a resistance to the widely used genes from the common soil bacteria Bacillus thuringiensis (Bt).
  • According to Biotech Articles, "Genetically engineering crops which tries to improve nutrition ignores the root cause of malnutrition,which are nothing but the industrial monoculture crops showing deterioration of the nutritional value of food. This leads to the destruction of a natural and agricultural biodiversity on which a healthy balanced diet depends."
