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).
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 …
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 …

mRNA code and translation (article) | Khan Academy
AUG is another special codon, as along with adding methionine during transcription, it also acts as the initiation or start codon. The process of translation starts at the AUG codon.
Overview: Eukaryotic gene regulation (article) | Khan Academy
Although all stages of gene expression can be regulated, the main control point for many genes is transcription. Later stages of regulation often refine the gene expression patterns that are "roughed …
