Known for his discovery of pneumococcal transformation
were a bacteria changes its form and function.

Avery
suggested that DNA and not protein was the hereditary material of bacteria -
hela cell
hela
first immortal cells helped discover vaccine polio and research cancer and other diseases. Used to discover how humans will react to certain chemicals. -
George Gey
Gey was the one to discover hela and sent the cells all over the nation to help make new discoveries in the field.

Watson & Crick
They discovered the double helix of the DNA. THey published their research and described the sequence.
Molecular structure -
Rosalind Franklin
She is best known for her defraction pictures of DNA strands RNA and viruses.Her work led to the discovery of the double helix
Rosalind -
crystalize dna
wilkensDNA was first crystalized in the early seventies further proving watson and crick right on what the dna strand looks like. -
boyer and cohen
they developed ways to combine and transplant genes in plants.
They created genetic engineering. -
First test tube baby
Louise Brown was created in a petri dish and placed in her mother. -
Dr.Alec Jeffreys
Dr.Jeffreys discover that each person had different lengths of VNTRs and each person was uniqe to them unless you are a genetic twin. This technique even helped police find and arrest a rapist. -

DNA first used in a criminal case
In florida Tommie Lee Andrews was the first person to be convicted using DNA during a trial -
Dolly the sheep
Dolly the sheep was the first mammal cloned from an adult cell using nuclear transfer she lived for 6 years and had 6 offspring

Erwin Chargaff
He created two rules that led to the discovery of the double helix first the number of guanine units equals the number of cytosine units, and the number of adenine units equals the number of thymine units. This hinted at the base pair makeup of DNA. second the amount of bases varies from species to species
Erwin Chargaff -
Human Genome Project
The project was to map the genes for members of our species. It was the first time we could read the complete set of blue prints for humans.

enzymes
a new enzyme was discovered that could repair dna strands better than scientists thought possible.It does it without forcing the damaged part on to the outside or backbone. -
double meaning
codons Dr. John Stamatoyannopoulos was leader of the team of scientists that discovered some of the codons has a second use. Some control cells to. -
recombinant DNA technology
this technology has resulted in the creation of things like insulin taxol and alot more. Scientists are even experimenting with plants to make them more resilent.
