Lecture 6PT 5 NUCLEIC ACIDS Flashcards
Nucleic Acids include
DNA + RNA
Nuelci Acids monomer is
nucleotides
3 Parts of a nuclic Acids
1) Phosphate group (po42-) 2) Pentane Sugar 3) Nitrogenous Base
Pentose Sugars (2)
Deoxyribose sugar and ribose sugar
diff between ribose and deoxy
Ribose has oxygen attacthed to 2nd carbon
Nitrogenous Base (2)
Single Rings, Double Rings
Single Rings
Pyridamines ( Cy, thy, ura)
Double Rings
purines (AG)
