DNA timeline

Gregor Mendel published the reults of the inheriance of pea plants

Mar 7, 1866

His expiriment revolutionized the discussion on genetics. zhis theory was linked off of hybrids and breeding.

William Bateson

Mar 9, 1905

Coined the owrd "genetics." He was the first one to start calling it genetics after a couple of expiriments involving genetics.

Avery put killed strain bacteria into a test tube

Mar 8, 1943

This is important because it gives expiriments on actual mice that were injected with different viruses.It is also important because it trggered a coupe of other expiremnts that tweaked it.

Watson and Crick discover the chemical structure of DNA

Mar 7, 1950

This is important to science because it shows what the DNA looks like. The were the ones to start calling DNA the double helix.

Chargaff discovers DNA composition in different species.

Mar 8, 1950

It is important to science because it shows how different species DNA can vary on what specie they are. Chargaff was hugly impacted by this and so was his career.

Franklin photographs crystalized DNA fibers.

Mar 8, 1952

This is important to science because it led to the inderstanding of DNA. It also was a major achievement at a time when only men were alowed in some universities dining rooms.

Hershey and Chase

Mar 8, 1952

This is important because they workes with phages in DNA. They also infected baceria with viruses.

The genetic code was discovered

Mar 7, 1966

It helped predict the characteristics while studying DNA. Leads to genetic engineering.

Louise Brown

Jul 25, 1978

This is important to science because she was the first ever test tube babie. he has caused a chain reactiona nd over 1 million childeren have been born using this procedure.

DNA was first used in a court case

Mar 9, 1986

Alec Jefferys had begun investigating the use of DNA for forensics. It was also used to verify DNA of different confessions of vivtims.

CRISPR

Mar 8, 1987

It is anew genome editing tool.It is important because it alowed scientists to edit genomes with percision, efficiency, and flexibility.

First time gene therapy is used on humans.

Mar 7, 1990

It uses genes to help prevent diseases. It replaces the mutated gene that made you sick with a new healthy gene.

Dolly the sheep was cloned for the first time

Mar 7, 1997

Helped scientists figure out you can clone some animals. It helped prove that cloning can actualy work on some cases.

First human chromose is decoded

Mar 8, 1999

It is important because it is the first time the full genetic code of a human chromosome was decoded. It contaned 33.5 million "letters."

John Sulston

Mar 9, 2000

He was most famous for finding out how cells in C. elegens divide. He is chair of the institute of science, ethics, and inovations.

Fianl completition of the human genome

Mar 7, 2003

It is the complete set of the nucleic acid sequence for humans. It encoded DNA with 23 chromosome pairs.

Animal and human cloning

Mar 9, 2009

Controversies continue over animal and human cloning on whether it is a good thing or a bad thing. There has been research on stem cells, and gentic makeup on crops so far.
