Title: Nucleic Acids 9-24-12

Nucleic Acids There are 2 main nucleic acids DNA RNA Both DNA & RNA are made of nucleotides, but their nucleotides are different Each Nucleotide has 3 parts 5 carbon sugar Phosphate group Nitrogenous base

Nucleic Acids DNA RNA 5 carbon Sugar Deoxyribose Ribose Phosphate group O -O -P –O -O - P –O Nitrogenous Base Adenine---Thymine Cytosine---- Guanine Adenine---Uracil Number of strands 2 strands of nucleotides 1 strand of nucleotides Shape Double helix Too many to list OH OH OH
