Q
Structure of bases
A
One purine pairs with one pyrimidine to maintain a constant distance between the 2 sugar-phosphate backbones.
-2 H bonds between A-T
-3 H bonds between C-G

Q
DNA vs mRNA
A
-DNA=Deoxyribose sugar
-RNA=Ribose sugar
-DNA=2 strands

-DNA=Thymine
-RNA=Uracil
-DNA=Replicates + stores genetic info
-RNA=Carries out instructions encoded in DNA.
4
Q
