What's the difference between unstack and unstick?
Unstack
Definition:
(v. t.) To remove, or take away, from a stack; to remove, as something constituting a stack.
Example Sentences:
(1) The observed inhibition of cation-induced spillover change was presumably due to loss of ability of these photosynthetic membranes to undergo unstacking in low-salt medium.
(2) Under catalysis-limited conditions, the imino proton exchange rates are predicted from the catalytic rate constants, prevailing buffer catalyst concentrations, and the equilibrium constants to form the unstacked open state of optical melting theory.
(3) Apparently the ribose-phosphate chain provides an essential contribution to the stiffness of oligomers and polymers, even when the bases are unstacked.
(4) Circular dichroism technique also shows that the interaction of p10 with RNA involves an unstacking of the nucleotide bases and an unfolding of the RNA secondary structure.
(5) The enthalpy change accompanying this pH-induced unstacking is +2.65 kcal (mole of A-A stack)-1 as measured by batch calorimetry.
(6) However, a comparison with the average length of stacked residues evaluated from available thermodynamic parameters of base stacking indicate that unstacked residues are not completely flexible.
(7) In control experiments, isolated, intact Golgi stacks were stable at 4 degrees C and 20 degrees C for > or = 1 h; however, some unstacking occurred at 32 degrees C. Treatment of intact Golgi stacks with a variety of proteolytic enzymes resulted in a time- and dose-dependent unstacking of the cisternae, although stacks were resistant to various other proteases.
(8) Binding causes relatively small chemical shift changes for the base resonances in adenylyl nucleotides, suggesting that there is some, but not complete, unstacking of the bases.
(9) A third step, which is very temperature dependent and which is very rapid at 37 degrees C, was postulated to involve the unstacking of DNA base pairs that immediately precedes open complex formation.
(10) Moreover, comparison between photosystem 1 and photosystem 2 electron transport and the effects of membrane unstacking suggest that low gramicidin D preferentially inhibits photosystem 2, while palmitic acid inhibits more effectively photosystem 1 coupling sites.
(11) Although the individual nucleosides are like those of B-DNA, their unstacked conformation, which is inappropriate for base pairing, as well as the conformational angles alpha and gamma of dA and zeta of dT, rule out B-DNA.
(12) The linkage also limits the number of cyclic hydrogen bonding configurations, and a model is proposed to describe a fraction of unstacked FAD in aqueous solution.A parallel study was made of NAD(+) and its analogues; in contrast to FAD, no clear evidence of cyclic hydrogen bonding was obtained with the pyridine coenzymes.
(13) Changes in the supramolecular organization of CD3 thylakoids, seen with freeze-fracture electron microscopy, include a reduction in the size of EFs particles, which correspond to photosystem II centers with variable amounts of attached LHCII, and a redistribution of EF particles from the stacked to the unstacked regions.
(14) We show that ELIP is integrated into the membranes via the unstacked stroma thylakoids.
(15) The result is consistent with the data from computer graphics modelling studies [39] which show that DNA-breathing (transient base pair unstacking) has to occur to allow the docking of the 1,5-disubstituted anthraquinone (VII) into the receptor site.
(16) Partition in an aqueous Dextran-polyethylene glycol two-phase system has been used for the separation of chloroplast membrane vesicles obtained by press treatment of a grana-enriched fraction after unstacking in a low salt buffer.
(17) When pea grana thylakoids were unstacked, the high temperature transitions were sharpened and their reversibility was enhanced.
(18) Membrane stacking is also absent in the ac-31 strain, and, when isolated in a low-salt medium, these membranes remain unstacked and exhibit only Bu and Cu faces.
(19) Because only the dye monomer binds to GS, the difference spectrum between dye and dye bound to GS is due in part to GS-promoted shifts in the equilibrium between stacked and unstacked dye molecules.
(20) It is projected that in aqueous solution, conformations of the individual nucleotidyl units of yeast tRNAhe are confined to the classically stable domains in the base stacked region and non-rigid flexible structures populate in the unstacked region comprising D16, D17, G20, U47 and A76.
Unstick
Definition:
(v. t.) To release, as one thing stuck to another.
Example Sentences:
(1) The manoeuvre consists after determination of the position that elicits the vertigo to move the whole head and body together of the patient to a 180 degree opposite position in which the addition to the endolymph flow forces and weight forces of the material will unstick it from the cupula.
(2) After that soak off the cover slip with alcohol, post-fix the squashed preparation together with cellophane in alcohol for 5-10 min, unstick the cellophane, pass the preparation through alcohol once again and dry it.
(3) Secondly when the superficial tension forces are too high the heavy material unstick from the cupula and it goes back to its normal position.
(4) "We are determined as a coalition government to unstick that market, to get the market moving."
(5) David Cameron and Nick Clegg have announced the introduction of taxpayer-backed 95% mortgages as part of a package of measures to help "unstick" the housing market and make the "dream of home ownership" a reality for more people.
(6) And its bloody unsticking in the recent period has come from a convergence of separate but connected issues.
