Sentence examples for virus stage from inspiring English sources

John B. S. Haldane, in his essay on the origin of life (Haldane 1929), extended that operational view to a more phylogenetic view, asserting that "life may have remained in the virus stage for many millions of years before a suitable assemblage of elementary units was brought together in the first cell".

In contrast, several other PLV encode the newly identified OLV11-like tyrosine recombinase and thus can be predicted to lead a dual, Polinton-like life style combining a virus stage with an integrated stage, similar to the Polintons.

It is interesting to note that this concept of pre-cellular evolution reverberates with Haldane's early vision: "...life may have remained in the virus stage for many millions of years before a suitable assemblage of elementary units was brought together in the first cell" [ 47].

Most viruses stage this coup by fusing with the cell membrane to insert their DNA or entering the cell whole via small membrane vessels.

The amount of PERV gag DNA copies in the parental cells were more than 100 times lower than that in human 293T cells, indicating that there is a major block in the early virus entry stage (Figure 1C, open bars).

The initial virus incubation stage is difficult to assess before an individual is symptomatic since it usually occurs without clinical manifestations.

They also discovered that the λ-carrageenan and moderately cyclized μ/ ι-carrageenan isolated from Gigartina skottsbergii exert promising antiviral activities towards diverse strains of HSV-1 and HSV-2 during virus attachment stage [ 37, 38].

In Epstein-Barr virus latent stage genes appear to deoptimize codon usage perhaps to reduce competition with host cell translation [ 25] and papillomavirus codon usage appears optimized for expression in certain cell types [ 26].

Empirical experiments appear to be a reliable approach used to determine the optimal condition for both cell growth and virus replication stages.

Next, we assessed co-receptor usage of SHIV-1157ipEL with late stage virus SHIV-1157ipd3N4 and clade B NL4-3 virus as controls.
