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 …

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.
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 …
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 …
Transcription and mRNA processing - 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, …

Aperçu de la transcription (leçon) | Khan Academy
La transcription d'un gène se fait en trois étapes : l'initiation, l'élongation et la terminaison. Ici, on va rapidement étudier comment ces étapes se déroulent chez les bactéries.
