Nucleotides

Cards (21)

  • There are two types of nucleic acid molecules: DNA and RNA.
  • The basic structure of a nucleotide is made of a sugar molecule, either RNA or DNA, attached to a phosphat group and a nitrogen-containing base
  • Nitrogenous bases can be purines (adenine and guanine) or pyrimidines (cytosine, thymine, uracil)
  • Purines are larger and have a one-ringed structure
  • Pyrimidines are smaller and have a two-ringed structure
  • When a nucleotide is assembled, each nitrogenus base is attached to one or more phosphate groups.
  • Pyramidines are: Thymine, cytosine, and guanine
  • Purines are; guanine and adenine
  • Ribonucleic acids contain ribose as their sugar component
  • Cytosine only pairs with guanine
  • Phosphate groups are represented by orange circles
  • A phosphate group, links neighboring sugars in a nucleic acid
  • The base only carries the coded genetic message in a nucleic acid
  • Deoxyborise sugar is found in DNA
  • Ribose sugar is found in RNA
  • ATP is a nucleotide that provides chemical energy for metabolism
  • When a nucleotide is forming it causes condensation which removes water
  • In a fromation of a nucleotide , a phosphoric acid base are chemically bonded to a sugar molecule by condensation reactions in which water is gvenoff. The reverse action is called hydrolysis
  • Nucleotides has 3 components; a base, sugar, and phosphate
  • Nucleotides are the building blocks of nucleic acids
  • The combination of bases in the nucleotides making up DNA or RNA stores the information controlling the cell's activity
