Rosalind Franklin
Found the first picture
Watson and Crick
Come up with that DNA has a double helix
Chargaff
Founded complementary base Paris and proved that A+T=C+G
Double helix
The shape of DNA
Backbone of DNA
Made up of alternating sugar and phosphate molecules
Complementary Base Pair
1. A and T, 2. C and G
Helicase
Breaks down hydrogen bonds and straightens DNA out, un-zips it
Ligase
Connects Okazaki fragments in lagging strands
DNA Polymerase
Starts where RNA primase lays down sequence
RNA Primase
Lays down a short sequence of RNA
Single Strand Binding ProteinsKeeps the DNA apartNucleotidesMonomers of DNA, sugar, phosphate, nitrogen bases, a lot together makes a polymer of DNASemiconservative ReplicationHalf of original parent, and acts as a mold for the DNALeading StrandContinuously made, working towards the forkLagging StrandMade in fragments, works away from fork, only build in short Okazaki fragmentsOkazaki FragmentsThe little pieces on the lagging strandAntiparallel orientationHow 2 strand are orientated in opposite directions, bases are complementary but one strand has 5' to 3', other has 3' to 5'
