Sentence examples for modification of pre from inspiring English sources

H/ACA box snoRNAs guide the pseudouridylation while C/D box snoRNAs guide the site specific 2'-o-ribose 2'-o-ribose 2'-o-ribose transcriptional methylationn of pre rRNA [ 2- 4].

Our phenomenological triplet model of long-term modification of pre- and postsynaptic components has three synaptic traces, two postsynaptic (y+ and y−) and one presynaptic (x+), which increase upon a post- or presynaptic spike, respectively (see Appendix 1 for a more detailed comparison with the triplet model (Pfister and Gerstner, 2006)).

A novel approach to uniformly bulk graft modification of pre-existing polymer materials without ungrafted homopolymers was achieved at relatively low temperature by means of gamma -rays pre-irradiation-induced "grafting-from" polymerization with supercritical carbon dioxide (scCO2) both as solvent and as swelling agent.

Unlike systems such as ventral marginal zone explants from Xenopus embryos and lateral or posterior mesoderm explants from chick embryos, the AC/AE model does not rely on modification of pre-existing posterior mesoderm, as cardiac mesoderm is induced de novo by the signals from the relevant source, gastrula-stage anterior endoderm.

(3) The QIAamp Stool Mini Kit procedure included the manufacturer's optional pre-treatment step of heating samples in a water bath at 95°C for 10 min, with a prior modification of pre-filling tubes with glass beads and ASL buffer, and disrupting the cells using a Precellys®24 ribolyser at 5500 cycles per min for 30 sec.

Although polyadenylation is a common modification of pre-mRNA, it is achieved by different mechanisms in different organisms [ 10- 12].

While the early phase is caused by rapid release or modification of pre-existing proteins, the delayed phase requires synthesis of new proteins [ 43, 44].

Many authors have proposed that certain self-incompatibility mechanisms may have arisen through the modification of pre-existing pathogen defense mechanisms [ 60].

This result indicates that majority of the storage TAG molecules in ND cells are accumulated through the modification of pre-existing lipids, rather than de novo synthesis.

The impact on survival of the modification of pre-therapeutic staging by the use of MRI has not yet been evaluated.

The mechanisms of cell division in multicellular tubes closely resemble those seen in planar epithelial sheets: following actomyosin ring ingression and membrane furrowing, new junctions between the daughter cells are formed through the modification of pre-existing ones.
