    Ancient introns may have marked RNA subsets in the RNA world, aiding function differentiation before DNA. This research explores their role in early life and origin.

    Area of Science:

    • Origin of Life Studies
    • Molecular Evolution
    • Biochemistry

    Background:

    • The discovery of RNA enzymatic activity led to the
    • RNA world
    • hypothesis, suggesting life predated DNA and proteins.

    Discussion:

    • The exon theory of genes posits introns are ancient genetic elements from the RNA world.
    • This communication examines RNA-protein world peculiarities and their impact on intron-exon structures.
    • We explore intron functions in DNA-lacking ancient cells and their role in life's origin.

    Key Insights:

    • Introns could have served as markers for distinct RNA subsets in ancient cells.
    • This marking system differentiated messenger RNAs from heritable genetic RNAs.
    • Introns may have directed RNA subsets to specific functions, crucial for early cellular processes.
