    Study Notes

    Types of Nucleic Acids

    • Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two main types of naturally occurring nucleic acids.
    • DNA serves as the primary information storage system in living organisms.

    Functions of Nucleic Acids

    • Nucleic acids are essential macromolecules crucial for the continuity of life.
    • RNA carries the genetic blueprint, facilitating the synthesis of proteins.

    Composition of Nucleic Acids

    • Nucleic acids are made up of units known as nucleosides.
    • Each nucleoside consists of a nitrogenous base, a sugar, and a phosphate group.

    Ideal Properties for Information Storage

    • An effective information storage system should have stability, the ability to store vast amounts of information, and fidelity in replication.

    Selection of DNA as Information Storage

    • DNA was chosen as the primary information storage system in nature due to its stability and capacity to hold complex genetic information.
    • Its structure enables accurate replication and transcription processes, essential for cellular function and heredity.
