| myogenic regulatory factors | A family of muscle-specific transcription factors which bind to DNA in control regions and thus regulate myogenesis. All members of this family contain a conserved helix-loop-helix motif which is homologous to the myc family proteins. These factors are only found in skeletal muscle. Members include the myod protein (myod protein), myogenin, myf-5, and myf-6 (also called mrf4 or herculin). (12 Dec 1998) |

| public utility regulatory policies act | (PURPA) A federal law requiring a utility to buy the power produced by a qualifying facility at a price equal to that which the utility would otherwise pay if it were to build its own power plant or buy power from another source. (05 Dec 1998) |
| sequence, regulatory | A sequence of bases in DNA that controls the expression of a gene. (12 Dec 1998) |
| sterol | <chemistry> Any steroid-based alcohol having a hydrocarbon (aliphatic) side-chain of 8-10 carbons at the 17-beta position and a hydroxyl group at the 3-beta position (therfore an alcohol). Cholesterol is a sterol. Because of its hydrophilic property at the -OH end and hydrophobicity at the hydrocarbon side chain, it can be incorporated into the lipid bilayers of the cytoplasmic membrane. However, sterols only exist in the cytoplasmic membranes of eukaryotes while in prokaryotes, virtually none have sterols in their membranes except mycoplasmas, a group of cell wall-less bacteria.
