  1. Overview of transcription - Khan Academy

    Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's …

  2. Stages of transcription: initiation, elongation & termination (article ...

    Transcription is an essential step in using the information from genes in our DNA to make proteins. Proteins are the key molecules that give cells structure and keep them running.

  3. Transcription factors (article) | Khan Academy

    General and specific transcription factors. Transcription initiation complex & looping. Combinatorial regulation.

  4. Transcription and mRNA processing - Khan Academy

    Transcription involves rewriting genetic information from DNA to mRNA, with RNA polymerase playing a crucial role. In eukaryotic cells, DNA to mRNA transcription occurs within the nucleus, producing pre …

  5. Overview of translation (article) | Khan Academy

    Step 1: transcription! Here, the DNA sequence of a gene is "rewritten" in the form of RNA. In eukaryotes like you and me, the RNA is processed (and often has a few bits snipped out of it) to make the final …

  6. The lac operon (article) | Khan Academy

    The CAP binding site is a positive regulatory site that is bound by catabolite activator protein (CAP). When CAP is bound to this site, it promotes transcription by helping RNA polymerase bind to the …

  7. The trp operon (article) | Khan Academy

    When the repressor binds to the DNA of the operator, it keeps the operon from being transcribed by physically getting in the way of RNA polymerase, the transcription enzyme.

  8. DNA replication and RNA transcription and translation

    Replication creates identical DNA strands, while transcription converts DNA into messenger RNA (mRNA). Translation then decodes mRNA into amino acids, forming proteins essential for life functions.

  9. Eukaryotic gene transcription: Going from DNA to mRNA

    In cells, transcription is the process that resembles copying a recipe onto a 3x5 card and sliding it under the office door. The 3x5 card, with the recipe written on it, is analogous to a messenger RNA …

  10. Transcription and mRNA processing (article) | Khan Academy

    During transcription, a gene's nucleotide sequence (DNA) is copied to form messenger RNA (mRNA), which serves as a temporary blueprint. In eukaryotes, this occurs in the nucleus.
