Father of modern Genetics
He was very interested in pea plants because they were easy to distinguished, and grow fast. He noticed that the traits could be tracked from one generation to the next. -
Conjugating bacteria
He studied how the DNA can travel from one bacteria to another. -
there's more than just tetraneuclotide blocks
He found that every neuclotide of DNA is similar in species, but even within species, none of them is equal. -
the blender experiment
Martha Chase and Alfred Hershey worked on a labaratory with phages; those are viruses that attack bacteria. -
DNA structure
Discovered that DNA is the hereditary molecule of the cell, and that the molecule functions as a code. They are able to direct synthesis of proteins. -
Replication experiement
Meselson and Stahl showed that new DNA is made by copying from the old. Each daughter cell must receive a faithul copy of the parent cell's DNA. -
DAN polymerase
Kornberg made a cell-free system that ruplicates DNA. He found that replication only occurs when all four nucleotides are present. Omit one, and polynucleotide chains are not synthesized. -
Messenger RNA
Sydney Brenner showed that rRNA was not the template for building proteins. There was a third type of RNA, an unstable intermediate that carries the DNA to the ribosme. After several experiments with bacteria his theory came up true, and he ccalled the new type: messenger RNA -
Fruit fly development
They looked at the development of the fruit fly, which goes through several distinct stages of development. -
Human genome
Craig Venter found that genes only make up 3% of our genome, and he figured out a faster and cheaper method of finding them.
