Macromolecules: Nucleic Acids Flashcards
(46 cards)
Polymer
A large molecule made up of repeating subunits
Monomer for Nucleic Acids
Nucleotides
what is a nucleotide
The building block of nucleic acids (DNA) and (RNA)
The three parts of a nucleic Acid
- Phosphate Group
- Five-carbon sugar
- Nitrogenous Base
Five-Carbon sugar
Deoxyribose (DNA) or ribose (RNA)
Phosphate group function
Provides a negative charge
Nitrogenous base
A molecule containing nitrogen that acts as a building block of Nucleotides
Purine
Double-ring Structure, Adenine and Guanine
Pyrimidines
Single-ring structure, cytosine, Thymine, and Uracil
Adenine
Purine, bonds to Thymine (T) or Uracil (U)
Guanine
Purine, bonds to Cytosine (C)
Cytosine
Pyrimidine, bonds to Guanine (G)
Thymine
Pyrimidine, bonds to Adenine (A), only in DNA
Uracil
Pyrimidine, bonds to Adenine (A), only in RNA
Nitrogenous base links to which Carbon
The First Carbon
Which Carbon links to the phosphate group
The Fifth Carbon
Ribose
Five carbon sugar in RNA
Deoxyribose
Five Carbon sugar found in DNA
Polymerization
Polymerization is the process by which monomers link together to form large macromolecules (polymers) through chemical reactions
Condensation Reaction
A condensation reaction is when two molecules combine to form a larger molecule, releasing a small molecule like water (H₂O)
Hydrolysis
Hydrolysis is a chemical reaction in which water (H₂O) is added to break down a larger molecule into smaller components.
ATP
ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various biological processes.
ATP uses
ATP is required for linking amino acids into proteins.
ATP is involved in the polymerization of nucleotides to form DNA and RNA.
ATP Energy Key points
Energy is stored in the high-energy bonds between phosphate groups.
Hydrolysis of ATP releases energy by breaking the bond between the second and third phosphate group
