What is the role of DNA in Biotechnology?

DNA in Biotechnology can be used to catch criminals, for instance, if you wanted to find a criminal, you could used fingerprint samples and use their fingerprint DNA to find them.

How is Biotechnology used in DNA testing?

  • Carrier screening
  • Confirming diagnosis of symptoms
  • Determining gender;
  • Forensic/identity testing;
  • Newborn screening;
  • Presymptomatic testing for estimating the risk of developing cancers;
  • Presymptomatic testing for predicting disorders.

How is Biotechnology used in agriculture?

DNA is now being used to change plants and crops. Genetically changing these crops is beneficial because they can make the plants strong to fight diseases. Not only plants, but animal breeds have also been improved with the help of genetic engineering techniques. With DNA in Biotechnology, both plants and animals benefit.

Agricultural and Food Scientist

Agricultural and food scientists work to make sure that food is safe. Most agricultural and food scientists work in research universities, private industries, or the federal government. They work in offices, and laboratories.The average yearlypay for agricultural and food scientists was $58,610 and an hourly rate of $28.18(As of May 2012). Agricultural and food scientists need at least a bachelor’s degree, but many get a doctoral degree. Food scientists and technologists and soil and plant scientists usually earn bachelor’s degrees and animal scientists earn a Ph.D.

How is Biotechnology used in the health industry in making medicine like penicillin and insulin?

Biotechnology has been around medicine for many years. The discovery of penicillin was made by Alexander Fleming in 1929. He saw that Staphylococcus aureus were killed when they accidentally came together with Penicillium notatum. After the dangerous cells were removed, Alexander Fleming published a piece of work about the germ. Penicillin wasn't commercaily available until the 1940s. Before Fleming's discovery, antimicrobial compounds were used to treat syphilis and other diseases, but they were given out as a chemical.

Some Biotechnology research centers in North Carolina...

  • North Carolina Biotechnology Center

  • NCCU's Biomanufacturing Research Institute and Technology Enterprise (BRITE)

How is Biotechnology used in environmental clean-up (Bioremediation)?

Some methods in Bioremediation is Dye Remediation, which is the clearing out of dyes from water sources. Bioremediation clean-ups can also help out with the cleaning of certain materials, such as pesticides, surfactants, wood preservatives, heavy metals, ect. Many companies have focused on on making biotechnological methods to clear out these dangerous materials.

What are the Potential negative impacts of Biotechnology?

Some negative affects of biotechnology is concern that genetically altered foods could lowering vitamin content or other nutrients. Some think a reaction might occur between two food compounds that could be toxic when mixed together. Others think that having genetically altered crops could affect the vegetative food chain, could decrease or increase the population of a species.
