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 …
Stages of transcription: initiation, elongation & termination (article ...
An in-depth looks at how transcription works. Initiation (promoters), elongation, and termination.
DNA transcription and mRNA processing (video) | 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 …
Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan Academy
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 RNA (mRNA).
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.
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 …
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 …
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 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, and we're …
