- Band, chromosome
Band, chromosome: One of the transverse bands produced on chromosomes by differential staining techniques. Depending on the particular staining technique, the bands are alternating light and dark or fluorescent and nonfluorescent. Each human chromosome has a short arm (“p” for “petit”) and long arm (“q” for “queue”) separated by a centromere. The ends of the […]
- Band, Q
Band, Q: 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.
- Banding of chromosomes
Banding of chromosomes: Treatment staining of chromosomes to reveal characteristic patterns of horizontal bands. Thanks to these banding patterns, which resemble bar codes, each human chromosome is distinctive and can be identified without ambiguity. Banding also permits the detection of chromosome deletions (lost segments), duplications (extra segments), and other structural abnormalities.
- Bannayan syndrome
Bannayan syndrome: A genetic disease characterized by macrocephaly (enlarged head), multiple lipomas (benign fatty tumors) and hemangiomas (benign blood vessel tumors). The macrocephaly occurs without enlargement of the cerebral ventricles. There is mild neurological impairment and postnatal growth retardation. Less frequent features associated with the syndrome may include antimongoloid (upslanting) palpebral fissures (eye slits), high-arched […]
