trait inheritance

Mar 8, 1850

Mendel selected 22 different varieties of peas and interbred them, keeping track of seven different traits, such as pea texture — smooth or wrinkled. Mendel found that when he hybridized smooth and wrinkled peas, he produced peas that were all smooth. But if he then produced a new generation of peas from the hybrids, a quarter of the peas were wrinkled.

mendel publishes work

Mar 8, 1866

He published his work in 1866, demonstrating the actions of invisible “factors”—now called genes—in providing for visible traits in predictable ways.

DNA

Mar 8, 1869

DNA first called nuclein identified by Friedrich Miescher as an acidic substance found in cell nuclei

rediscovery

Mar 8, 1900

Mendel's experiments from 1866 are "rediscovered"

experiments

Mar 8, 1903

First experiments on quantitative traits in broad beans by Wilhelm Johanssen and in wheat by Herman Nilsson-Ehle.

genes

Mar 8, 1905

some genes are linked and do not show independent assortment, as seen by Bateson and Punnett.

avery

Mar 9, 1930

Avery was the most deserving scientist to not receive the Nobel Prize for his work,[6] though he was nominated for the award throughout the 1930s, '40s, and '50s.

genes

Mar 9, 1941

One gene encodes one protein, as described by Beadle and Tatum.

Chargaff

Mar 9, 1950

claiming that molecular biology was "running riot and doing things that can never be justified"

hersey&chase

Mar 9, 1952

series of experiments conducted in 1952[1] by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material.

Watson & Crick

Mar 9, 1953

In early 1953, Pauling published an incorrect triple helix model of DNABoth Crick, and particularly Watson, thought that they were racing against Pauling to discover the structure of DNA.

dolly the sheep

Mar 9, 1966

She was created using the technique of somatic cell nuclear transfer, where the cell nucleus from an adult cell is transferred into an unfertilized oocyte (developing egg cell) that has had its cell nucleus removed. she had three mothers

test tube baby

Mar 9, 1978

the first test-tube baby, Louise Brown, was born. Robert Edwards and Patrick Steptoe, who were both responsible for the birth,

franklin

Mar 9, 1982

After finishing her work on DNA, Franklin led pioneering work at Birkbeck College, London, on the molecular structures of viruses.[6] Her team member Aaron Klug continued her research, winning the Nobel Prize in Chemistry in 1982.

Human Genome

Mar 9, 2001

The human genome was the first of all vertebrates to be completely sequenced. As of 2012, thousands of human genomes have been completely sequenced, and many more have been mapped at lower levels of resolution.

CRISPR

Mar 9, 2002

In 2000, similar repeats were identified in other bacteria and archaea.[15] SRSR was renamed CRISPR in 2002 after a suggestion from Mojica.[14][16] CRISPR was proposed to be responsible for the generation of adaptive immunity in microbes.

fingerprinting

Mar 9, 2016

Lynda Mann was abducted in Narbourough, England. The next day, her body was discovered raped and murdered. Three years later, another young woman met the same fate near Lynda’s resting place. Richard Buckland was arrested and confessed to the second murder only. An untested technique was applied; ‘genetic fingerprinting’ through DNA analysis.

Biotechnology

Mar 9, 2016

Biotechnology is the use of living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use
