Gregor Mendel
Founder of modern science and genetics. Pea plant expiraments established many rules of heredity, now known as the laws of Mendelian inheritance. Mendel's work proved the genotype and phenotype of pea plants. -
Rosalind Franklin
This young women in science was an English chemist and x-ray crystallographer. She made contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal, and graphite. Although she competed other research, DNA was her most recoginized one. She worked in London with other scientist, -
Avery- Macleod- McCarty
This expirament showed that DNA is what causes bacterial transformation. In the era before, it was believed that protien served the function of carrying genetic information. The research accumulated from the 1930's through the 40's. -
Wikins
Born in 19416, Mauric eHugh Fredrick Wilkins was a New Zealand-English physicist and moecular biologist. His research contricuted to the understanding of of phosphorescence, isotope serparation, optical microcopy and x-ray diffraction, later developing the radar. He is known for his work in London about the three distinct phases of DNA structure. -
Hershey- Chase
A series of expiraments were conducted throug the year 1952 by Alfred Hershey and Martha Chase that helped determine that DNA is the genetic material. Since 1869, biologists believed protien was what carried the information. When bacteriophages infect bacteria, their DNA enters the host cell, but their prootien does not, -
Watson- Crick
"Molecular Structure of Nucleic Acids: A Structure fr Deoxyribose Nucleic Acid" was an article published by Francis Crick and James Watson in 1953. It was the first published thing which discussed the descovery of the double helix structure of DNA. They used x-ray diffraction and the mathematics of a helix transform. -
GMO
The first recombinate DNA molecules were produces by Paul Berg. Genetic engineering, the direct result of manipulating genes using biotechnology was discovered by Herbert Boyer and Stanley Cohen in 1973. GMO is geneticall modified organisms which creates genes that are more fit for thier enviornment making them the the fittest, -
polymerase chain reaction
Developed by Kary Mullis, PCR is a common biological technique used for variety of applications. These include DNA cloning for sequencing and analyzing genes. This method depends on the thermal cycling, consisting off specific heats needed to complete its proccess. -
Cloning- Animals
This term describes several different proccesses that can be used to prode geneticall identical copies of a biological antity. The copied material which has the same gentic makeup as the orginal, is reffered to a clone. Scientists began cloning small animals like mice and moved to bigger things lik sheep. They successfully created a sheep Dolly, an exact replica of it's mother, Dolly. -
LAVIN WAS BORN
I felt the need to be included in this timeline of biological accomplishments :-)
