A1.2 Nucleic acids SL Flashcards
Nucleotide
Pentose sugar
Organic compounds in living cells formed by nucleotide chains, notably DNA and RNA
Nucleic Acids
Two strands of DNA never touch each other and are oriented in opposite directions
Antiparallel
Portion of the DNA double helix that provides structural support to the molecule and consists of repeating linked sugar and phosphate molecules (within nucleotides)
DNA or Phosphate Backbone
Type of reaction that links polymers via the condensing of a water molecule, seen in DNA and RNA backbone construction
Condensation Reaction
Nitrogen Base: A
Adenine, found in both DNA and RNA

Uracil, found only in RNA
Nitrogen Base: G
Guanine, found in both DNA and RNA
Deoxyribose sugar, two strands, bases ATGC
Unique properties of DNA
Nitrogen Base: T
Thymine, found only in DNA
