Do you know that the manipulation of proteins through genetic engineering can lead to the discovery of various advancements in biotechnology? Gene splicing is an important milestone in genetic engineering. The most common animals used for vaccine safety testing are pigs, monkeys, rats and so on. These animals can be used as genetically engineered animals for their use in agriculture or pharmaceuticals. Biotechnology gave rise to use of microorganisms in milk and milk products. Biotechnology is the area of research and study of living organisms and their products. It has significant use in our day to day life. Red biotechnology is the field of developing pharmaceuticals including vaccines. Bioweapons, which are used to cause diseases and toxins are also included in this field. Medical biotechnology uses living cells or tissues to produce pharmaceutical products. Biotechnology provides information about genetic composition of human DNA so that it is possible to discover new medicines and repair damaged genes.
