Bi 1d: Central Dogma
Bi 5a: DNA, RNA, protein structure and function
Bi 5b: Base pairing rules
Nitrogen baseI’m the A,T,C,G or Upart!
Are nucleic acidscharged molecules?
Purine = AG
Matching bases?Why is this important?
H bonds?Why is this important?
Matching halves?Why is this a good system?
“It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.”
A = 30.9%
T = 29.4%
G = 19.9%
C = 19.8%
RulesA = T
C = G
That’s interesting!What do you notice?
Where do these processes occur in the cell?
