Sentence examples for expressed only a single from inspiring English sources

However, these experiments were performed with only one serotype that expressed only a single member of the M protein family (i.e., pattern A) and the possibility that LTA might form complexes with other proteins was not investigated.

RNA-DNA FISH showed that the majority of single cells expressed only a single allele.

Transgenic mouse strains were backcrossed with Rho−/− mice so that these rods expressed only a single type of rhodopsin (Lem et al., 1999).

In contrast, in our previous deletion experiments hybrids expressed only a single endogenous copy of either mel-Lhr or sim-Lhr.

In some species, GH 45 genes have rapidly propagated and diversified (e.g. Leptinotarsa decemlineata), while in other cases, the insect expressed only a single copy of this gene (e.g. G. viridula and C. tremulae).

The complex mechanisms that control c-myb gene expression must not play a role, and the results cannot be due to different activities of variant isoforms produced through alternative RNA splicing, since the lentivirus vector expresses only a single, full-length cDNA of c-Myb and is not subject to the controls that regulate c-myb gene expression.
