Basic Regulation of Eukaryotic Transcription Initiation

There are some subtle errors in the video.

0:24 - There is no one "activator" protein. Activator proteins constitute an entire class of proteins that can help turn on certain genes and bind certain DNA sequences, if they are present. But all help initiate transcription of their target genes in some way.

1:01 - In the same way, there is no one "repressor" protein. Repressor proteins are also another large class of proteins that have the ability to somehow halt the initiation of transcription at certain genes, if they are present.
