History of Genetics
We have learned a great deal in the field of genetics over the last century. Many scientists have spent their whole lives studying genetics. These scientists discovered many vaccines and cures for diseases. We now have a better understanding of how heredity, DNA, chromosomes, and many other things play a part in every life. The first group of scientists that started work with genetics was focused on working with vaccines. Edward Jenner started this with the discovery of a vaccine for small pox. That discovery impacted society greatly because many lives were saved. Many more vaccines came about after that discovery. Another great discovery of this time wa
This field is still being expanded on. He also formed the theory of independent assortment, the principle of segregation, and invented the terms dominant and recessive. Jefferys invented doing DNA fingerprinting through electrophoresis. She then realized that we could genetically engineer chromosomes to cure diseases of unborn children. We now began answering questions about DNA: what it was, why we have it, and what we could use it for. Barbara McClintock worked with corn and discovered that they had "jumping genes". They then expanded on her work and realized that the double helix was formed of pairs of proteins, such as adenine and guanine. She worked with x-ray diffraction and discovered the double helix. Rosaline Franklin started the work done with DNA. This meant that genes would move to different chromosomes. s the realization of how characteristics are inherited. He realized that females have XX chromosomes, and the males have XY. More work was done by many scientists to understand what chromosomes were for and what they did. He didn't really know what the chromosomes were for.
