Study Notes

Nucleic Acid Building Blocks

  • Phosphate Group

    • Chemical formula: PO4

  • Ribose

    • A five-carbon sugar found specifically in RNA

  • Deoxyribose

    • A five-carbon sugar that serves as a component of DNA nucleotides

  • Purine (Adenine)

    • One of the two types of nitrogenous bases in nucleic acids, important for DNA and RNA structure

  • Purine (Guanine)

    • Another type of nitrogenous base found in both DNA and RNA, pairs with cytosine

  • Pyrimidines (Cytosine)

    • A nitrogenous base found in both DNA and RNA; pairs with guanine

  • Pyrimidines (Thymine)

    • Unique to DNA, pairs with adenine, crucial for DNA structure

  • Pyrimidines (Uracil)

    • Found only in RNA; replaces thymine and pairs with adenine

  • Nucleic Building Blocks Found Exclusively in DNA

    • Contains deoxyribose and thymine

  • Nucleic Building Blocks Found Exclusively in RNA

    • Comprises ribose and uracil

  • Common Components Found in Both DNA and RNA

    • Include adenine, guanine, cytosine, and phosphate groups
