Document Summary
In this video, we"ll continue our discussion on gene specific. And up until now, we"ve been talking mostly about how individual genes are. Now we"ll go up a level in the hierarchy and talk about circuits of genes. 3082 three different types of circuits; positive feedback, a toggle switch, and a feed forward loop. 3083 see how clusters of genes are regulated. 3084 [00:00:23. 32] we"ll talk a little bit about epigenetic regulation, which is a mechanism we haven"t. And lastly, we will talk about experimental methods for studying gene. 3086 circuits; both dna sequences and dna binding proteins. And those were examples 3087 of shutting things down when there"s. In here, we"re going to look at a positive feedback loop. 3089 is thought of as a memory device, in the sense. What we"re going to see is if you make a little of. 3090 protein a, you will continue to make it.
