Gene Regulation
... Some genes are regulated (turned off and on) by repressor proteins While others use proteins that enhance the rate of transcription. Operons are generally not found in Eukaryotes. Gene regulation is controlled individually and have regulatory sequences that are much more complex that those of the la ...

Epigenetics: We often discuss genes as if their presence in our cells
... Epigenetics: We often discuss genes as if their presence in our cells assures that they will be expressed. This is not true. The expression of genes is highly regulated. That is to say that our genes can be turned on or off, and this can be good (most of the time) or bad (sometimes). We understand t ...
