Document Summary
In today"s series of videos, we"re going to talk about gene. In the previous class, we talked about general features of transcription and. What genes, in general, have to happen for genes to get turned on or off. 2728 enough to be able to turn genes on or off. You have to turn on selective genes when you want. 2729 them, and keep others off when you need them to be off. 2730 [00:00:27. 82] so this is about a higher level of control. And the very basic switch in that control. 2731 is a dna binding protein binding to a dna specific sequence to turn a gene on that"s right in. And that"s how a gene can be activated. 2734 [00:00:56. 12] we"ll look at some of the molecular details, in terms of how proteins contact dna, 2735 which i say is reading the code of the dna in the major and minor grooves to recognize this is.
