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 …

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.
Transcription factors (article) | Khan Academy
Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.
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 …
Les étapes de la transcription (leçon) | Khan Academy
La transcription est une étape essentielle de l'exploitation des informations génétiques de notre ADN pour fabriquer des protéines. Les protéines sont les molécules clés qui structurent les cellules et les …
