These plasmids often carry other antibiotic resistance genes, heavy metal resistance genes and/or other pathogenic factors such as toxins, hence the selection for any of these factors selects for the plasmid.
Fluoro-orotic acid (FOA) has a selective toxicity for cells expressing URA3, hence SC/FOA selects for the repressed state of URA3 and confirms variegated expression.
The results showed that re-circularisation of the linearised plasmid had occurred in 5 out of the 6 occasions, which usually leads to loss of linearised DNA because the drug pressure applied selects for the presence of the circular plasmid containing the selectable marker.
Positive selection for transfectants was achieved using 5 nM WR99210, an antifolate that selects for the presence of the human dhfr gene [27].
The key worker selects for the child a number of these interventions".
And the Savoie wines his wife Magali selects for the cellar are a revelation.
Clean racing selects for the best horse; the most durable, soundest, best developed, best bred, and fastest horse.

Stuart Pearce has insisted he has complete control over who he selects for the Great Britain Olympic football team at London 2012 after being appointed as the head coach.
This "directed evolution" induces mutations in genes and selects for the best among them over several rounds, generating multitudes of new variants in a fraction of the time that nature would require.An extension of directed evolution culls several different beneficial mutations and assembles them together in the same gene, with the aim of obtaining an additive or synergistic effect.
Antibiotic usage selects for the accumulation and spread of antibiotic-resistant bacteria.
