What is biotechnology...
- DNA is the genetic material of all living organisms and all organisms use the same genetic code. Genes from one kind of organism can be transcribed and translated when put into another kind of organism.
- Each human cell contains a copy of DNA, allowing analysis to be performed on samples from hair, skin, blood, sweat, saliva and semen.
- Biotechnology uses microorganisms, such as bacteria or yeasts, or natural(biological) substances, such as enzymes, to perform specific industrial or manufacturing processes.
Biotechnology has a wide variety of uses...
Biotechnology in agriculture allows the transfer of useful characteristics (such as resistance to a disease) into a plant, animal or microorganism by inserting genes (DNA) from another organism. Virtually all crops improved with transferred DNA now have been developed to aid farmers to increase productivity by reducing crop damage from weeds, diseases or insects.
- Bioremediation works by providing pollution-eating organisms with fertilizer, oxygen, and other conditions that encourage their rapid growth. These organisms would then be able to break down organic pollutant at a correspondingly faster rate, this ability can be used to clean up oil spills.
- The global fight for market share is leading companies to massively deploy genetically altered crops around the world (more than 30 million hectares in l998) without proper advanced testing on short- or long-term impacts on human health and ecosystems the could have the possibility of causing major effects on health. Antibiotics placed in plants to fend off disease can cause antibiotic resistant bacteria.
