(n.) A substance capable of crystallizing in several distinct forms; also, any one of these forms. Cf. Allomorph.
Example Sentences:
(1) Structural peculiarities in tubulin polymorphism are considered.
(2) We conclude that only one of the alleles was amplified and that either allele could be amplified with respect to both the SphI and PvuII polymorphisms.
(3) Twelve families with Wiskott-Aldrich syndrome (WAS) were studied by linkage analysis using 10 polymorphic marker loci from the X-chromosome pericentromeric region.
(4) Restriction fragment length polymorphisms (RFLPs) were studied in a large Algerian family which includes 6 haemophiliacs and a previously described case of female haemophilia A.
(5) 247 individuals from Northern Italy have been tested for red cell glutamic-pyruvic transaminase (GPT) polymorphism.
(6) An N-acetylation polymorphism is described that is expressed toward arylamine carcinogens in tumor target organs of an inbred rat model.
(7) These killer cells could lyse a wide range of syngeneic and allogeneic lymphoid tumour cell lines in vitro, and it was found that cell suspensions from nude mice were always significantly more active than those from normal mice, and that the most active effector population was a polymorph-enriched peritoneal-exudate cell suspension.
(8) Analysis of Alu repeat polymorphism should be useful in construction of a high-resolution map and also in identifying genotypes of individuals for clinical and other purposes because the repeats are ubiquitous and the technique for their detection is simple.
(9) Structurally altered polymorphic variants with reduced activity, such as tetrameric interface mutant Ile-58 to Thr, may produce not only an early selective advantage, through enhanced cytotoxicity of tumor necrosis factor for virus-infected cells, but also detrimental effects from increased mitochondrial oxidative damage, contributing to degenerative conditions, including diabetes, aging, and Parkinson's and Alzheimer's diseases.
(10) Subcutaneous polymorphic sarcomas were induced in 8 out 27 offspring of syrian golden Hamsters after treatment of pregnant mother animals at day 15 of gestation with Adenovirus 12.
(11) Because all differences were found only in this region of the molecule, and because DR alpha-chains seem to be relatively non-polymorphic, these positions in the DR beta-chain must have a major role in influencing T-cell recognition of the DR molecule.
(12) The dense polymorphous bodies of the B pinealocytes are ultrastructurally identified as lysosomes.
(13) Multiple polymorphisms on the DQ molecule(s) have been detected by monoclonal antibodies (MoAbs).
(14) The PvuII-CIII and PvuII-AIV polymorphisms were both associated with differences in apo AI levels, explaining 3.7%-5.7% of the sample variance.
(15) Affinity constants, binding kinetics and serum concentrations of hSHBG from individuals having a 4-band pattern were similar to those obtained in individuals with a 2-band pattern, thus suggesting that the mechanism responsible for the generation of polymorphic variants of hSHBG reported herein did not involve the steroid binding site of the molecule.
(16) Polymorphism of PGM1 and PGM3 types was investigated in placental extracts from 127 unrelated Japanese parturients living in Yamanashi Prefecture.
(17) Genomic, cDNA, and cosmid probes have been used to isolate homologous cosmids from human chromosomes 7, 10, 16, 17 and X as part of a search for polymorphic nucleotide sequences.
(18) A family with occurrence of juvenile sudden death and effort polymorphous ventricular tachycardias is reported.
(19) As an extension to the variety of existing techniques using polymorphic DNA markers, the Random Amplified Polymorphic DNA (RAPD) technique may be used in molecular ecology to determine taxonomic identity, assess kinship relationships, analyse mixed genome samples, and create specific probes.
(20) We report that specific human (dC-dA)n.(dG-dT)n blocks are polymorphic in length among individuals and therefore represent a vast new pool of potential genetic markers.
Polymorphous
Definition:
