    Study Notes

    Heredity and Nucleic Acids

    • Heredity is the passing of traits or characteristics from parents to offspring through genes.

    Chromosomes

    • Chromosomes are thread-like structures made up of DNA and proteins that carry genetic information.

    Nucleic Acids

    • Nucleic acids are biomolecules that contain the genetic instructions used in the development and function of all living organisms.
    • There are two main types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
    • Proteins are not a type of nucleic acid.

    DNA

    • DNA is responsible for storing and transmitting genetic information from one generation to the next.
    • DNA is present in the cells of all living organisms, specifically in the chromosomes of the cell nucleus.
    • The main function of DNA is to provide a blueprint for the development and function of an organism.

    RNA

    • RNA plays a crucial role in the transmission of hereditary information by carrying genetic information from DNA to the ribosomes, where proteins are synthesized.

    Characteristics of Nucleic Acids

    • Nucleic acids are capable of replication and transmission of genetic information.
    • They are resistant to degradation and can withstand high temperatures.
    • They are sensitive to ultraviolet (UV) light.
    • Nucleic acids are not capable of catalyzing chemical reactions.
