BIOL 101 Lecture Notes - Lecture 14: Polynucleotide, Thymine, Pyrimidine
Document Summary
Is a hereditary molecule passed from parents to offspring. Single dna molecule wrapped around a protein (histone) Information is stored in nucleotides (thymine, guanine, adenine, cytosine; uracil in place of thymine in rna) Watson and crick got credit for the discovery of the shape and structure of dna. They used franklin"s image to further their research (without her knowledge) W & c received a nobel prize while f did not not due to her death. Franklin received no recognition until ten years after her death. Like a rope ladder twisted in a spiral. Assumes this structure because it saves space and protein interactions. Major and minor grooves (major= where protein interactions occur) **bacteria and other microorganisms store info in such a small space due to proteins which help supercoil dna. All the genetic info that defines an organism. Separate double stranded into 2 single strands. Make covalent bonds between nucleotide of a new dna strand.
