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 …
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 …
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 …
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.

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.
Differences in translation between prokaryotes and eukaryotes
But, in eukaryotic cells, things are a little bit different. So transcription... happens in the nucleus, and translation happens in the cytoplasm where there are ribosomes. And so the mRNA, after …
