What's the difference between crick and jackscrew?
Crick
Definition:
(n.) The creaking of a door, or a noise resembling it.
(n.) A painful, spasmodic affection of the muscles of some part of the body, as of the neck or back, rendering it difficult to move the part.
(n.) A small jackscrew.
Example Sentences:
(1) This suggests that (AGG)12 can form intra- and inter-molecular complexes by non-Watson-Crick, guanine:guanine base-pairing.
(2) It is demonstrated that this peculiar DNA fragment, under suitable conditions of concentration, salt and temperature, exclusively prefers to adopt a monomeric hairpin form with a stem of three Watson-Crick type base pairs and a loop of two residues.
(3) Hope u feel better xx” Bird told Channel 4’s political editor Michael Crick: “Natasha Bolter and I were in a consensual relationship between 18 September and 2 November, well after her admission to the list of approved candidates.
(4) The new Francis Crick Institute in London, now filling with 1,400 scientists, could be built and run for 10 years on that.
(5) The Watson-Crick H-bonded imino proton resonances were studied.
(6) The Watson-Crick alignment of the alkylG.T and alkylT.G mispairs may facilitate formation of these phosphodiester links, and this alignment rather than the strength of the base pairs and the extent of hydrogen bonding between them may be the crucial factor in the miscoding.
(7) The complex has one drug molecule intercalated between Watson--Crick base pairs of the nucleotide duplex.
(8) Recognition of the UACUAAC box thus relies, at least in part, on Watson-Crick base pairing with the yeast U2 analogue.
(9) A characteristic of Watson-Crick paired A X T and G X C bases is the pseudo 2-fold symmetry axis in the plane of the base pairs.
(10) The imino proton of T3 in the O6meG.T 12-mer and G3 in the O6meG.N 12-mer helix, which are associated with the modification site, resonate at unusually high field (8.5 to 9.0 ppm) compared to imino protons in Watson-Crick base pairs (12.5 to 14.5 ppm).
(11) We’d get recognised when we went out, and I developed a bad crick in my spine because I was staring at the pavement so much.
(12) The base pairing between piA and poly(U) in this system is probably of the Hoogsteen type (involving the 6-amino group and N7 of 3-isoadenosine) rather than of the Watson-Crick type.
(13) One of these models is a four-strand structure in which two duplexes of the Watson-Crick kind are specifically related by a twofold rotation axis and which has already been discussed in some detail.
(14) Nurse, too, believes the Crick is built on solid foundations.
(15) Molecular modeling shows that a stereochemically satisfactory structure can be build using C2'-endo sugars and a displacement of the Watson-Crick base-pair center from the helix axis of 2.5 A. Helical constraints of rise per residue (h = 3.26 A) and residues per turn (n = 12) were taken from fiber diffraction experiments of Arnott and Selsing (1974).
(16) The temperature variation of the imino proton NMR signals suggests that the hydrogen bonding in self-recognition is comparable in strength with that in a beta-DNA duplex, and NOE data are in accord with Watson-Crick rather than Hoogsteen base pairing.
(17) We describe NMR studies at superconducting fields which characterize aspects of the structure and stability of the 1 : 2 actinomycin-d-pG-C complex in solution as monitored at the Watson-Crick base pairs and backbone phosphate groups.
(18) From fibre diffraction data, models for triplex structures with poly(U).poly(A).poly(U) and poly(dT).poly(dA).poly(dT) have been proposed, in which the purine and one pyrimidine strand are Watson-Crick paired in an A' helix, and the other pyrimidine strand is Hoogsteen base-paired parallel to the purine strand along the major groove.
(19) The peptide forms a parallel, two-stranded coiled coil of alpha helices packed as in the "knobs-into-holes" model proposed by Crick in 1953.
(20) 7.09pm: On his blog, Newsnight's Michael Crick quotes an unnamed Liberal Democrat MP who told him he was amazed how much the Tories were willing to compromise.
Jackscrew
Definition:
(n.) A jack in which a screw is used for lifting, or exerting pressure. See Illust. of 2d Jack, n., 5.
Example Sentences:
(1) Scanning electron microscopy morphometric analysis found major evidence of ERR in the tooth-borne jackscrew appliance, in the long-term group, in the maxillary premolars, on the buccal and furcation root surfaces, on the mesiobuccal root, and in the apical zone.
(2) Three subjects received one of the following appliances: (1) conventional type jackscrew maxillary plate bonded to the posterior teeth with a high force magnitude of 2033 g, (2) a similar tooth-borne appliance but with rare earth repulsive magnets having a low force of 258 g, or (3) a specially designed palatal acrylic appliance pinned directly to the palatal shelves also utilizing rare earth repulsive magnets with a low force of 258 g. A fourth animal, the control, received a passive sham appliance bonded to the abutment teeth.
(3) The animals were divided into short-term and long-term groups, and were treated with jackscrew, magnetic and sham palatal expansion appliances.
(4) With the conventional jackscrew high-force appliance bonded to the teeth, the treatment lasted 33 days.
