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 …
Stages of transcription: initiation, elongation & termination (article ...
An in-depth looks at how transcription works. Initiation (promoters), elongation, and termination.
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, …
Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan …
The molecule that's directly made by transcription in one of your (eukaryotic) cells is called a pre-mRNA, reflecting that it needs to go through a few more steps to become an actual messenger …
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 …

Les étapes de la transcription (leçon) | Khan Academy
Un examen approfondi du fonctionnement de la transcription. Initiation (promoteurs), élongation et terminaison.
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 …
Stages of translation (article) | Khan Academy
To use a little molecular biology vocab, these antibiotics block translation. In the process of translation, a cell reads information from a molecule called a messenger RNA (mRNA) and …
Types of RNA (article) | Khan Academy
This article summarizes the different types of RNA, including more well-known RNA like tRNA and ribosomal RNA, and less-known RNA like siRNA that also contribute to cell function.
