  2. 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 …

  3. 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.

    Early experiments on the genetic code Central dogma of molecular biology Central dogma - revisited Eukaryotic gene transcription: Going from DNA to mRNA Transcription and mRNA processing mRNA …

  5. 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.

  6. Regulation of transcription (video) | Khan Academy

    This process involves transcription factors, activators, enhancers, repressors, and silencers. Prokaryotes rely on gene regulation for environmental adaptation, while eukaryotes have more complex …

  7. 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 …

  8. DNA transcription and mRNA processing (video) | Khan Academy

    Transcription is when we take the information encoded in the gene in DNA and encode essentially that same information in mRNA. So transcription we are going from DNA to messenger RNA, and we're …
