BIOL 101 Lecture Notes - Lecture 8: Maurice Wilkins, Nucleoid
Document Summary
Rna uses the host machinery to replicate itself. In eukaryotes, nucleic acids are found in the nucleus and cell organelles including mitochondria and chloroplasts of plants. In prokaryotes (e. g. bacteria) the dna is not enclosed in a membranous envelope but is located in a specialized cell region called the nucleoid. 1935: discovery of the 3d structure of dna by watson and crick. Dna was discovered in the 1800s by meisner. 4 scientists contributed essentially to the discovery of the 3d structure the double helix structure rosalind franklin and maurice wilkins. They essentially captured the images of the molecule itself. x-ray diffraction and were able to capture images of the dna molecule. Two people got a lot of credit for it: james watson and francis crick. Using x-ray diffraction, they were able to visualize the structure of dna and.
