    Study Notes

    Satellite Repetitive DNA Sequences

    • Also referred to as transposons
    • Contrary to their name, composed of repetitive sequences that occur in multiple copies
    • Not typically gene-rich regions, but rather transcriptionally inactive
    • Characterized by tandem repeats, which can be classified based on the number of repeats
    • Classified into different types based on the size of the repeat unit

    Activation of Amino Acids for Translation

    • Involves preparation for protein synthesis
    • Requires specific steps to enable amino acid incorporation into polypeptide chains
