Sentence examples for removal of selection from inspiring English sources

This proposal would yield random partitioning; a result not obviously compatible with analyses of the rate at which cells lose oriP vectors following removal of selection and become susceptible to being killed on reapplication of the selective agent (Yates et al, 1984; Kirchmaier and Sugden, 1995).

This hierarchy is produced via iterative removal of selection units (cells) using the criterion of least marginal loss of conservation value to decide which cell to remove next.

It should also be noticed that taking into account the effective one-dimensional Coulomb interaction leads to the destruction of the previous symmetry of the task and to the full removal of selection rules for the oscillatory quantum numberN.

Upon removal of selection pressure, either by discontinuation of PrEP [23] or transmission to a drug naïve individual [28], the drug-resistant mutants decline after a period of persistence, due to outgrowth by wild-type virus (reversion) [29] [31].

In addition, the strategy should preferentially incorporate two commonly used site-specific recombination systems, Cre/loxP [2] and Flp/FRT [12], to allow versatile possibilities for the removal of selection cassettes in mouse ES cells or animals [3].

If so, removal of selection for behavioural traits related to female fitness (e.g., yeast foraging) should lead to more masculine patterns of behaviour in both sexes when they express male-limited evolved genomes, with opposite effects on fitness.

This can be considered to have come about by the removal of natural selection for effective dispersal, and once removed metabolic 'expenditure' on these structures is reduced.

More advanced knockout constructs additionally carry loxP sites on both sides of the Bsr cassettes for subsequent removal of the selection marker by transient expression of Cre recombinase, thus allowing generation of multiple knockouts using just a single selection marker.

Indeed, we were unable to detect the FLPe construct by PCR at 3 weeks after the removal of BSD selection (data not shown).

However, removal of the selection marker from the genome by partial Cre activity in vivo is complicated, time-consuming and may be gene-dependent [1], [2].

Full commercialization of the described process would require removal of antibiotic selection, for instance by integration of the heterologous mevalonate pathway into the genome [27], and use of an alternative induction system that did not require the expensive inducer IPTG.
