  • Regulation of Eukaryotic DNA Transcription

    Regulation of Eukaryotic DNA Transcription

    Animation

    (2 min 5 sec) General transcription factors, activators, and repressors interact to regulate the transcription of eukaryotic DNA into RNA.

  • DNA transcription (advanced detail)

    DNA transcription (advanced detail)

    Animation

    (1 min 55 sec) The process of copying DNA into messenger RNA (mRNA) is called transcription. Transcription factors assemble at the promoter region of a gene, bringing an RNA polymerase enzyme to form the transcription initiation complex. Activator proteins at the enhancer region of DNA then activate the transcription initiation complex. RNA polymerase unzips a small portion of the DNA and copies one strand into an mRNA molecule. Also available in Spanish.

  • DNA transcription (basic detail)

    DNA transcription (basic detail)

    Animation

    (1 min 55 sec) The first phase of the process of reading DNA information to make proteins starts with a molecule unzipping the DNA. The molecule then copies one of the strands of DNA into a strand of RNA, a close cousin of DNA. This process is called transcription. Also available in Spanish.

  • Structure and Function of Telomeres

    Structure and Function of Telomeres

    Click & Learn

    This mini-lesson covers the research on telomeres that has happened since the 1995 Holiday Lectures.

  • Life at the End of the Chromosome: Another RNA Machine

    Life at the End of the Chromosome: Another RNA Machine

    Lecture

    (58 min 20 sec) The chromosome ends, or telomeres, are necessary for DNA stability and replication.
