Friedrich Miescher |
characterized proteins from pus cells |
|
|
Friedrich Miescher |
isolated a molecule from the nucleus and called it nuclein |
|
|
Ernst Haeckel |
who said : “the obvious cellular component of the cell is the nucleus” ? |
|
|
Edmund Wilson |
used staining technique to study karyokinesis of ovum
important nuclear element from cell to cell : DNA |
|
|
Edmund Wilson |
used staining technique to study karyokinesis of ovum
important nuclear element from cell to cell : DNA |
|
|
Rosalind Franklin, Gosling & Maurice Wilkins |
Found out that helical DNA structure, sugar, and phosphate background outside, while nucleotides are tucked inside |
|
|
James Watson and Francis Crick |
Found out about triple helix, and that phosphate is in the center (pero lol mali naman haha nice try gg) |
|
|
Linus Pauling |
proposed triple helix (epal) |
|
|
John Griffith |
Proposed that nucleotides are flat, stack up on top of another, and the possibility of A=T, C=G pairing.
Crick saw the importance of specific pairing in replication process. |
|
|
Erwin Chargaff |
proposed Chargaff’s rule
claims that purine-pyrimidine ratio is 1:1 |
|
|
Jerry Donohue |
Claimed that hydrogen in the bases can change its position. (It may be responsible for the Hydrogen bonding) |
|
|
Molecular Structure of Nucleic Acid
and
Genetic Implications of the Structure of Deoxyribuncleic Acid |
2 Publications of Watson and Crick |
|
|
James Watson, Francis Crick, and Maurice Wilkins
(Rosalind Franklin was robbed frfr) |
Who were the ones who received a nobel prize? |
|
|
Frederick Griffith |
transformation experiment using Streptococcus pneumoniae
transformed avirulent strain to virulent
declared the presence of transforming principle |
|
|
Oswald Avery, Colin Macleod, Maclyn McCarty |
Physician-Scientists
identified the transforming principle (TP) as DNA |
|
|
Alfred Hershey and Martha Chase |
used the blender experiment
proved that the DNA is the genetic material of bacterial viruses which is injected into the cell during infection |
|
|
Norton Zinder and Joshua and Esther Ledenberg |
used transduction experiment in Salmonella typhimurium to further prove that DNA is the genetic material |
|
|
Rosalind Franklin, Maurice Wilkins, James Wateson, and Francis Crick |
Discovered the structure of the DNA
(elucidated the DNA structure) |
|
|
Francis Crick |
had PhD in Biophysics and worked on xray studies of proteins at Cambridge University |
|
|
James Watson |
PhD in Microbiology from Univ of Indiana then moved to Cambridge Univ. then shared office with Crick |
|
|
Maurice Wilkins |
PhD in Physics worked on radar and Manhattan Project and asst. Director of Med Research at Kings College, London
He worked on x-ray diffraction of DNA. |
|
|
Rosalind Franklin |
Expert on x-ray diffraction techniques and joined Kings College in 1951 to work on x-ray diffraction of DNA |
