Structure of DNA
pictures…
structure of pyrimindes and purines
three h bonds between c & g bonds stronger
mice and strains
first experiment to discover DNA
hershey and chase bacteria
2nd experiment
unwinds double helix
helicase
adds complementary abses to leading strand (5’-3’)
dna polymerase III
adds RNA primer to lagging strand
primase
adds complementary bases to lagging strang (okazaki fragment)
dna polymerase II
removes rna primer and replaces with complementary bases
dna polymerase I
connects adjacent okazaki fragments
ligase
SSB
okazaki fragments
leading strand
lagging strand
