Nucleotide Structure & Nucleic Acid polymerization Flashcards
1
Q
what 3 components are present in all nucleotides
A
nitrogenous bases, phosphate group, deoxyribose
2
Q
what are the two classes of nitrogenous bases and what bases are within each class? how can you tell the two classes apart visually
A
purines (adenine & guanine) and pyrimidines (cytosine, thymine, uracil); purines are double ringed while pyrimidines are single ringed
3
Q
what are the two possible 5 carbon sugars that can be part of nucleotide? how do they differ structurally
A
deoxyribose & ribose, ribose has a hydroxyl group while deoxyribose does not
4
Q
what kind of reaction links nucleotides together in chitin
A
phosphodiester bonds
