| 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) |
|---|---|
| overlapping reading frame | <molecular biology> Start codons in different reading frames which generate different polypeptides from the same DNA sequence. (09 Oct 1997) |
| trial frame | A type of spectacle frame with variable adjustments, for holding trial lenses during refraction. (05 Mar 2000) |
| eulerian frame | <radiobiology> Reference frame which has a fixed coordinate system, as opposed to the Lagrangian Frame, which moves with a fluid. (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) |
| Foster frame | A reversible bed similar to a Stryker frame. (05 Mar 2000) |
| frame | 1. To construct by fitting and uniting the several parts of the skeleton of any structure; specifically, in woodwork, to put together by cutting parts of one member to fit parts of another. See Dovetail, Halve, v. T, Miter, Tenon, Tooth, Tusk, Scarf, and Splice. 2. To originate; to plan; to devise; to contrive; to compose; in a bad sense, to invent or fabricate, as something false. "How many excellent reasonings are framed in the mind of a man of wisdom and study in a length of years." (I. Watts) 3. To fit to something else, or for some specific end; to adjust; to regulate; to shape; to conform. "And frame my face to all occasions." (Shak) "We may in some measure frame our minds for the reception of happiness." (Landor) "The human mind is framed to be influenced." (I. Taylor) 1. Anything composed of parts fitted and united together; a fabric; a structure; especially, the constructional system, whether of timber or metal, that gives to a building, vessel, etc, its model and strength; the skeleton of a structure. "These are thy glorius works, Parent of good, Almighty! thine this universal frame." (Milton) 2. The bodily structure; physical constitution; make or build of a person. "Some bloody passion shakes your very frame." (Shak) "No frames could be strong enough to endure it." (Prescott) 3. A kind of open case or structure made for admitting, inclosing, or supporting things, as that which incloses or contains a window, door, picture, etc.; that on which anything is held or stretched; as: The skeleton structure which supports the boiler and machinery of a locomotive upon its wheels. A molding box or flask, which being filled with sand serves as a mold for castings. 4. <machinery> A term applied, especially in England, to certain machines built upon or within framework; as, a stocking frame; lace frame; spinning frame, etc. 5. Form; shape; proportion; scheme; structure; constitution; system; as, a frameof government. "She that hath a heart of that fine frame To pay this debt of love but to a brother." (Shak) "Put your discourse into some frame." (Shak) 6. Particular state or disposition, as of the mind; humor; temper; mood; as, to be always in a happy frame.

| absolute terminal innervation ratio | The number of motor endplates divided by the number of terminal axons related to them. (05 Mar 2000) |
| amino-terminal | <biochemistry> The end of a protein or polypeptide chain with the unattached amino group or the aminoacyl residue containing it. Each amino acid in the chain has an amino group on one side, which is attached to the carboxyl group (COOH group) of the previous amino acid, and a carboxyl group on the other side (which is attached to the amino group of the next amino acid). The other end of the polypeptide chain is called the carboxyl terminal. Synonym: NH2-terminal. (14 Aug 2000) |
| amino-terminal residue | <biochemistry> The only amino acid residue in a polypeptide chain that has a free alpha-amino group, it defines the amino terminus of the polypeptide. (09 Oct 1997) |
| axonal terminal boutons | The somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). As isolated, by homogenizing brain or spinal cord, they contain acetylcholine and the related enzymes. Terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods. See: synapse. Synonym: axonal terminal boutons, end-feet, neuropodia, pieds terminaux, synaptic boutons, synaptic endings, synaptic terminals, terminal boutons, bouton terminaux. (05 Mar 2000) |
| carboxyl terminal | The end of a polypeptide chain with the unattached carboxyl group (a -COOH group). Each amino acid in the middle of the chain has an amino group (a -NH2 group) on one side (which is attached to the carboxyl group of the previous amino acid) and a carboxyl group on the other side (which is attached to the amino group of the next amino acid). The other end of the polypeptide chain is called the amino terminal. (09 Oct 1997) |
| carboxyl-terminal residue | This amino acid residue defines the carboxylterminus of the polypeptide, its the only residue with a free alpha-carboxyl group. (09 Oct 1997) |
| carboxy terminal | The end of a peptide or protein having a free carboxyl (-COOH) group. (05 Mar 2000) |
| carboxy-terminal domain kinase | <enzyme> Protein kinase that phosphorylates the c-terminal repeat domain of the largest subunit of RNA polymerase II at serine residues Registry number: EC 2.7.1.- Synonym: ctd kinase, hs-ctd kinase, tfiih-associated ctd kinase (26 Jun 1999) |
