What are major discoveries that led to the development of modern biotechnology?
By mid-century, major advances in genetics dominated biotechnology research. The discovery that DNA carries the genetic code and the structure of the “double helix” were described by Watson and Crick. Soon, new techniques were developed to allow manipulation of DNA.

What was an invention that changed biotechnology forever?
DNA Polymerase (1956) In 1956, Arthur Kornberg and his lab forever changed the world of molecular biology with the discovery of DNA polymerase from E. coli cells. In one instant, scientists were now finally capable of synthesizing new DNA sequences onto an existing DNA strand.
What are some examples of modern day biotechnology?
For example, human insulin, a small protein used to treat diabetes, is made in genetically engineered bacteria, whereas large, more complex proteins like hormones or antibodies are made in mammalian cells or transgenic animals. Antibiotics and vaccines are products of microorganisms that are used to treat disease.
