  • Nucleic Acids
    • An organic compound whose molecules carry genetic information and is made up of one or two chains of monomer units called nucleotides
  • DNA
    • deoxyribonucleic acid
    • largest molecules in cells
    • carries all genetic information
    • double helix
    • nitrogenous bases
  • Nitrogenous Base Pairs
    • A-T
    • G-C
  • DNA Replication
    • Process by which an identical copy of the original DNA molecule is formed. The process begins when DNA un-zippers with the help of the helicase enzyme. The two strands are now separated and nucleotides make two new DNA molecules.
  • RNA
    • ribonucleic acid
    • synthesis of proteins
    • differs from DNA in the following ways:
      • ribose instead of deoxyribose
      • uracil instead of thymine (A-U is found in RNA whereas A-T is found in DNA)
      • single stranded
      • much smaller
  • RNA Synthesis
    • ribosomes are organelles that are composed of RNA and proteins
    • ribosomes are site of protein production
