2.4.5 Draw a simple diagram of the molecular structure of DNA
-show complementary C:G and A:T pairs-identify hydrogen bonds (hold bases together)-number of H-bonds between complementary bases not required-details of base structure not required
Your diagram can be simple, just remember that A and G are double rings; C and T are single rings.Sugar phosphate backbone goes on outside of “ladder”Bases are the “rungs of the ladder”hydrogen bonds between bases are in very center
Key to thispicture:1. hydrogen bonds inPINK2. Bases ingreen andpurple3. Sugarphosphatebackbone inblackPhosphates inyellow
