A form of chromosome band, one of the bright and dull fluorescent bands seen alternating along the length of chromosomes under ultraviolet light after the chromosomes are stained with quinacrine.
The Q in Q band stands for Quinacrine, an agent used as an antimalarial agent and, in the laboratory, as a fluorescent dye.
- q arm of a chromosome
The symbol “p” was chosen to designate the short arm because “p” stands for “petit”, “small” in French. The letter “q” was selected to signify the long arm merely because “q” is the next letter in the alphabet.

A potentially fatal viral infection that attacks the central nervous system. Rabies is carried by wild animals (particularly bats and raccoons) and finds its way to humans by many routes. Most cases of rabies can be traced to animal bites, but cases have been documented in which the virus was inhaled in bat caves, contracted […]
- Raccoon roundworm infection
Infection by the raccoon roundworm is also called Baylisascaris. The species commonly found in raccoonsis Baylisascaris procyonis. When infective eggs of this roundworm are ingested by humans, Baylisascaris larvae hatch in the intestine and travel through the organs and muscles. This is the larva migrans syndrome. Infected raccoons shed millions of eggs in their feces. […]
An ethnic stock or division of humans. Naturalists and ethnographers have long divided humans into a variable number of distinct races. However, DNA and other genetic studies have revealed that that most genetic variation, about 94%, is within so-called racial groups while these racial groupings differ from one another only in about 6% of their […]
