Mindblown: a blog about philosophy.

10-6 gram, or 2.527 x 10-8 ounce (avoirdupoir). A metric unit that is equivalent to one-millionth of a gram. A unit of measurement of weight equal to one millionth of a gram. One millionth part of a gram, or one thousandth part of milligram, designated by the symbol μg. A measure of weight; 1/1000 of…

Very thin filaments found in the cytoplasm of cells. Microscopic tube or filament within or between cells. Fibrils of the protein actin that form the cytoskeleton, which provides support and contributes to cellular movement.  

Any chemical that will kill microorganisms. Used synonymously with biocide and bactericide. Gels or creams that can be inserted into the rectum or vagina, designed to reduce the risk of anal or vaginal transmission of viruses such as HIV. The aim is to kill or to inactivate the virus, creating a barrier to mucosal cells…

The cell structure, growth factors, metabolism, and genetics of microorganisms.  

An organism that grows best in the presence of a small amount of oxygen.  

Refers to a DNA molecule that is saturated with methyl groups (i.e., methyl submolecule groups, —CH3, have attached themselves to the DNA molecule at all possible locations). Generally, when a DNA molecule is methylated, the genes comprising that DNA molecule are “turned off” (i.e., inactivated).  

The facilitated transport of a solute across a membrane, usually by a specific membrane protein (e.g., adhesion molecule).  

The midpoint of the temperature range over which DNA is denatured.  

To change from a solid to a nonsolid (e.g., liquid) state by the addition of heat (to the solid substance).  

Melting DNA means to heat-denature it. When this happens the hydrogen bonds holding the DNA molecule together in the normal way are disrupted, allowing a more random polymer structure to exist.
