Watson and Crick discover the shape and makeup of DNA
Watson and Crick are two college graduates who were studying the makeup and shape of DNA. With the help of Rosalind Franklin's photos, The two of them figured out the double helix shape of DNA with their models by figuring out the A,T,G,C connections. (JAN 1 is NOT the correct date) -

46 Human Chromosomes
Joe Hin Tjio discovered that 46 chromosomes is the exact number of cells in a human cell. -
DNA copying enzyme
Arthur Kornberg and his helpers isolated a DNA enzyme that would soon be used for DNA sequencing. -
mRNA Carries Info
Sydney Brenner, François Jacob and Matthew Meselson
discover that mRNA takes information from DNA in the
nucleus to the cytoplasm. -
First Animal Gene Cloned
Researchers copied frog DNA and were successful. -
First Transgenic Mice and Fruit Flies
Scientists successfully add stably inherited genes to laboratory
animals. This tested the functions of genes. -
Launch of the Human Genome Project
The Department of Energy and the National Institutes of
Health announce a plan for a 15-year project to sequence the
human genome. -
Mouse Genetic Map Completed
The lab mouse is valuable for genetics research because
humans and mice share almost all of their genes, and the
genes on average are 85% identical. -
Completion of the Human Genome Sequencing
The finished human genome sequence will be at least 99.99%
accurate.
