| albumin Reading | Types of human serum albumin, distinguished by characteristic mobility patterns on electrophoresis; each type is due to a mutation of a gene controlling albumin synthesis; the mutant genes are codominant with the normal gene for albumin A, and the group forms a system of genetic polymorphism; types include: albumin b (slow), found occasionally in persons of European ancestry; albumin Ghent (fast), found first at Ghent, Belgium; albumin Mexico (slow), found in Indians of Mexico and the southwestern United States; albumin Naskapi (fast), found in the Naskapi and other Indians of northern North America; and albumin Reading (fast), found first at Reading, England.

| blocked reading frame | A sequence of DNA that cannot be translated into a viable protein; usually due to the interruption by one or more termination codons. Synonym: closed reading frame. (05 Mar 2000) |
| reading frame | One of the three possible ways of reading a nucleotide sequence. As the genetic code is read in nonoverlapping triplets (codons) there are three possible ways of translating a sequence of nucleotides into a protein, each with a different starting point. For example: given the nucleotide sequence: AGCAGCAGC, the three reading frames are: AGC AGC AGC, GCA GCA, CAG CAG. (18 Nov 1997) |
| reading frame, open | An open reading frame in DNA has no termination codon, no signal to stop reading the nucleotide sequence, and so may be translated into protein. (12 Dec 1998) |
| reading frames | The sequence of codons by which translation may occur. A segment of mRNA 5'auccga3' could be translated in three reading frames, 5'auc.. Or 5'ucc.. Or 5'ccg.., depending on the location of the start codon. (12 Dec 1998) |
| reading-frameshift mutation | <molecular biology> A type of mutation that results from insertion or deletion of a single nucleotide into, or from, an open reading frame in the normal DNA sequence. Normally, the genetic code is read in the wrong frame, three nucleotides at a time, and the entire sequence downstream of the mutation, is translated into a polypeptide with a garbled amino acid sequence from the mutated codon onwards. These mutations may be induced by certain types of mutagens or may occur spontaneously and usually result in the generation, downstream, of nonsense, chain termination codons. Synonym: addition mutation, addition-deletion mutation, deletion mutation, reading-frameshift mutation. (21 Jun 2000) |
| mind-reading | The knowledge or communication by one person with the mental processes of another through channels other than known physical or perceptual processes. (12 Dec 1998) |
| closed reading frame | A sequence of DNA that cannot be translated into a viable protein; usually due to the interruption by one or more termination codons. Synonym: closed reading frame. (05 Mar 2000) |
| open reading frame | <molecular biology> A reading frame in a sequence of nucleotides in DNA that contains no termination codons and so can potentially translate as a polypeptide chain. (18 Nov 1997) |
| open reading frames | Reading frames where successive nucleotide triplets can be read as codons specifying amino acids and where the sequence of these triplets is not interrupted by stop codons. (12 Dec 1998) |
| overlapping reading frame | <molecular biology> Start codons in different reading frames which generate different polypeptides from the same DNA sequence. (09 Oct 1997) |
| unidentified reading frame | <molecular biology> A reading frame in a sequence of nucleotides in DNA that contains no termination codons and so can potentially translate as a polypeptide chain. (18 Nov 1997) |
| arch bar | Any one of several types of wires, bar's, or splints conforming to the arch of the teeth, extending from one side of the arch to the other and located labially, or lingually; used for the treatment of jaw fractures and/or stabilization of injured teeth. (05 Mar 2000) |
| bar | 1. A piece of wood, metal, or other material, long in proportion to its breadth or thickness, used as a lever and for various other purposes, but especially for a hindrance, obstruction, or fastening; as, the bars of a fence or gate; the bar of a door. "Thou shalt make bars of shittim wood." (Ex. Xxvi. 26) 2. An indefinite quantity of some substance, so shaped as to be long in proportion to its breadth and thickness; as, a bar of gold or of lead; a bar of soap. 3. Anything which obstructs, hinders, or prevents; an obstruction; a barrier. "Must I new bars to my own joy create?" (Dryden) 4. A bank of sand, gravel, or other matter, especially. at the mouth of a river or harbor, obstructing navigation. 5. Any railing that divides a room, or office, or hall of assembly, in order to reserve a space for those having special privileges; as, the bar of the House of Commons. 6. The railing that incloses the place which counsel occupy in courts of justice. Hence, the phrase at the bar of the court signifies in open court. The place in court where prisoners are stationed for arraignment, trial, or sentence. The whole body of lawyers licensed in a court or district; the legal profession. A special plea constituting a sufficient answer to plaintiff's action. 7. Any tribunal; as, the bar of public opinion; the bar of God. 8. A barrier or counter, over which liquors and food are passed to customers; hence, the portion of the room behind the counter where liquors for sale are kept. 9. An ordinary, like a fess but narrower, occupying only one fifth part of the field. 10. A broad shaft, or band, or stripe; as, a bar of light; a bar of colour. 11. A vertical line across the staff. Bars divide the staff into spaces which represent measures, and are themselves called measures. A double bar marks the end of a strain or main division of a movement, or of a whole piece of music; in psalmody, it marks the end of a line of poetry. The term bar is very often loosely used for measure, i.e, for such length of music, or of silence, as is included between one bar and the next; as, a passage of eight bars; two bars' rest. 12. <veterinary> The space between the tusks and grinders in the upper jaw of a horse, in which the bit is placed. The part of the crust of a horse's hoof which is bent inwards towards the frog at the heel on each side, and extends into the center of the sole. 13. <chemical> A drilling or tamping rod. A vein or dike crossing a lode. 14. A gatehouse of a castle or fortified town. A slender strip of wood which divides and supports the glass of a window; a sash bar. Bar shoe, a trial before all the judges of one the superior courts of Westminster, or before a quorum representing the full court. Origin: OE. Barre, F. Barre, fr. LL. Barra, W. Bar the branch of a tree, bar, baren branch, Gael. & Ir. Barra bar. 91. Source: Websters Dictionary (01 Mar 1998) |
| bar clasp | A clasp whose arms are bar-type extensions from major connectors or from within the denture base; the arms pass adjacent to the soft tissues and approach the point of contact on the tooth in a gingivo-occlusal direction, a clasp consisting of two or more separate arms located opposite to each other on the tooth; the bar arms arise from the framework or from a connector and may traverse the soft tissue; one arm (bar), the retentive arm, usually terminates in the infrabulge (gingival convergence) area of the tooth; the other, the reciprocal arm, usually terminates on the suprabulge (occlusal convergence) area. Synonym: Roach clasp. (05 Mar 2000) |
