Examples of noncoding in the following topics:

  • Noncoding DNA

    • The amount of noncoding DNA varies greatly among species.
    • For example, over 98% of the human genome is noncoding DNA, while only about 2% of a typical bacterial genome is noncoding DNA.
    • Other noncoding sequences have likely, but as-yet undetermined, functions.
    • Utricularia gibba, a bladderwort plant, has only 3% noncoding DNA .
    • Most of the genome size difference appears to lie in the noncoding DNA.

  • Molecular and Cellular Cloning

    • Cloning small fragments of the genome allows for the manipulation and study of specific genes (and their protein products) or noncoding regions in isolation.

  • Telomere Replication

    • After each round of DNA replication, some telomeric sequences are lost at the 5' end of the newly synthesized strand on each daughter DNA, but because these are noncoding sequences, their loss does not adversely affect the cell.
