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 …

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 …
