- Transcription: an overview of DNA transcription (article) | Khan Academy
In transcription, the DNA sequence of a gene is transcribed (copied out) to make an RNA molecule
- Stages of transcription - Khan Academy
An in-depth looks at how transcription works Initiation (promoters), elongation, and termination
- Les étapes de la transcription (leçon) | Khan Academy
Un examen approfondi du fonctionnement de la transcription Initiation (promoteurs), élongation et terminaison
- Transcription and mRNA processing - 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-mRNA This pre-mRNA undergoes processing, including the addition of a 5' cap, a poly-A tail, and splicing out introns, resulting in mature mRNA, which then leaves the nucleus for protein

En la transcripción, la secuencia de ADN de un gen se transcribe (copia) para hacer una molécula de ARN
- Etapas de la transcripción (artículo) | Khan Academy
Una revisión a fondo sobre cómo funciona la transcripción Iniciación (promotores), elongación y terminación
- Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan Academy
After transcription of a eukaryotic pre-mRNA, its introns are removed by the spliceosome, joining exons for translation The intron products of splicing have long been considered 'junk' and destined only for destruction
- Transcription and mRNA processing (article) | Khan Academy
Transcription: the synthesis of RNA from a DNA template The first stage of gene expression is transcription, during which a gene’s nucleotide sequence is transcribed, or copied, into an mRNA molecule The enzyme primarily responsible for transcription is RNA polymerase
