Hi Linrio
you write an essay for me that summarize watson and crick paper
Now , my doctor ask us to prove watson and crick paper ( because they didn’t do any experiment ) by other scientists that do experiments .
I will give you three scientists and I want to write about them and find one extra

1- Rosalind Franklin ( photo 51 for DNA improve the structure of watson and crick )
2-Chargaff’s rules ( he do an experiment that improve the number of A = T and G =C which watson and crick didn’t improve it )
3- konberg (improve the double helix run in opposite direction )
