| genetic code | <molecular biology> Relationship between the sequence of bases in nucleic acid and the order of amino acids in the polypeptide synthesised from it. A sequence of three nucleic acid bases (a triplet) acts as a codeword (codon) for one amino acid. (18 Nov 1997) |
|---|---|
| code | The genetic code is the correspondence between the triplet of bases in DNA with the amino acids. The discovery of the genetic code clearly ranks as one of the premiere events of what has been called the Golden Age of Biology (and Medicine). (12 Dec 1998) |
| soundex code | A sequence of letters used for recording names phonetically, especially in record linkage. (05 Mar 2000) |
| Strickland code | <zoology> A code of nomenclature for taxonomic classification prepared by a committee of the British Association for the Advancement of Science, first published in 1842. (09 Jan 1998) |
| degenerate code | <molecular biology> The fact that in most cases in the genetic code used by all life on Earth, one particular amino acid is specified by more than one three-base combination of the four nitrogenous bases (called a codon). There are enough different codons to specify 64 different amino acids, but there are in actuality only 20 amino acids (and three stop codons) used in the making of proteins. (09 Oct 1997) |
| International Code of Zoological Nomenclature | <zoology> An Authoritative document containing a system of rules and recommendations to be followed in giving a scientific name to an animal or animal group. Adopted by the International Congresses of Zoology and Administered by the International Commission on Zoological Nomenclature. The most recent version of the Code, adopted in principle by the 20th General Assembly of the International Union of Biological Sciences at Helsinki in 1979, was approved by the ICZN late in 1983. With minor exceptions it retains the same format as the first two editions. Minor amendments for immediate incorporation are published in Bulletin Zoological Nomenclature as Declarations to remain in force until ratified or rejected by future congresses. (09 Jan 1998) |
| uniform mechanical code | (UMC) A code sponsored by the International Association of Plumbing and Mechanical Officials and the International Conference of Building Officials, adopted and amended by the Oregon Department of Commerce. The UMC contains requirements for the installation and maintenance of heating, ventilating, cooling, and refrigeration systems. (05 Dec 1998) |
| Albright's hereditary osteodystrophy | An inherited form of hyperparathyroidism associated with ectopic calcification and ossification and skeletal defects, notably the small fourth metacarpals, but intelligence is normal. There are dominant, recessive and X-linked forms. See: pseudohypoparathyroidism. Synonym: Albright's syndrome. (05 Mar 2000) |
| angioedema, hereditary | A genetic form of angioedema. (Angioedema is also referred to as Quinke's disease.) Persons with it are born lacking an inhibitor protein (called C1 esterase inhibitor) that normally prevents activation of a cascade of proteins leading to the swelling of angioedema. Patients can develop recurrent attacks of swollen tissues, pain in the abdomen, and swelling of the voice box (larynx) which can compromise breathing. The diagnosis is suspected with a history of recurrent angioedema. It is confirmed by finding abnormally low levels of C1 esterase inhibitor in the blood. Treatment options include antihistamines and male steroids (androgens) that can also prevent the recurrent attacks. Also called hereditary angioneurotic oedema. (12 Dec 1998) |

| canine hereditary blindness | An autosomal dominant condition seen in dogs of the collie and several other breeds. (05 Mar 2000) |
| colourectal neoplasms, hereditary nonpolyposis | A syndrome characterised by autosomal dominant inheritance, a low mean age (41 years) for occurrence of colon cancer, and a marked increase in the proportion of tumours in the proximal colon. (12 Dec 1998) |
| corneal dystrophies, hereditary | Bilateral hereditary disorders of the cornea, usually autosomal dominant, which may be present at birth but more frequently develop during adolescence and progress slowly throughout life. Central macular dystrophy is transmitted as an autosomal recessive defect. (12 Dec 1998) |
| hereditary | <genetics> Transferred via genes from parent to child. (16 Dec 1997) |
| hereditary amyloidosis | <neurology> A disorder in which various peripheral nerves are infiltrated with amyloid and their functions disturbed, an abnormal prealbumin is also formed and is present in the blood; characteristically, it begins during mid-life and is found largely in persons of Portuguese descent. Other rare clinical types occur. Inheritance: autosomal dominant. Synonym: familial amyloidosis, hereditary amyloidosis. (05 Mar 2000) |
