Transcription: an overview of DNA transcription (article) | 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 …

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).
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 …

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.
Regulation of transcription (video) | Khan Academy
Now a few notes about the differences between prokaryotes and eukaryotes when it comes to transcriptional regulation. In prokaryotes, the regulation of transcription is really needed for the cell to …
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.
