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 gonna, in this video, focus on genes that code for proteins
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 interactions and a nuclear envelope for added control
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 maintiennent en marche
The lac operon (article) | Khan Academy The CAP binding site is a positive regulatory site that is bound by catabolite activator protein (CAP) When CAP is bound to this site, it promotes transcription by helping RNA polymerase bind to the promoter
Stages of translation (article) | Khan Academy To use a little molecular biology vocab, these antibiotics block translation In the process of translation, a cell reads information from a molecule called a messenger RNA (mRNA) and uses this information to build a protein Translation is happening constantly in a normal bacterial cell, just like it is in most of the cells of your body, and it's key to keeping you (and your bacterial
