discovery Flashcards
1
Q
who worked on the structure of the DNA
A
- Maurice Wilkins
- Rosalind Franklin
2
Q
how did they approach it
A
- looked at X-ray crystallography
- diffraction images of DNA
3
Q
what happened at the same time
A
- Cavendish institute of Cambridge
- Francis Crick
- James Watson
4
Q
what did Crick and Watson do
A
- used data from the DNA x-ray analysis
- built a model out of brass plates and clamps
- discovered nucleic acid formed in a twisted shape (double helix)
- have runners made of phosphates and sugars
- series of rungs made of pairs of organic compounds (bases)
5
Q
Watson and Crick
A
- developed ideas of genetic replication
- base pairings
- complementary strands and new chains
6
Q
Sydney Brenner and Francis Crick
A
- discovered proof of the triplet code used in reading genetic material in DNA
- transferring the information to RNA in cytoplasm where proteins are synthesised
7
Q
what did they prove
A
- DNA is a double-stranded molecule that could replicate exact copies of itself
- DNA could carry out genetic instructions
8
Q
nobel prize
A
- Watson, Crick and Wilkins
- Franklin did not get awarded for her research in finding all of this
- she died from cancer at the age of 37
- had a degree in chemistry
- reluctant to announce her findings until she was sure
