Adams, who, a little earlier, had been rocking delightedly in his seat, was now bent over his score with a tight expression, scribbling notes on a yellow pad.
In the coming months, I'd see some of them walking around with dried blood on their uniforms and a hard, tight expression on their faces.
Beth peered out from all this with a tight expression of superiority on her small flat face, as if to say that not many people could put up with such a nightmare as well as she could, even if the world wasn't generous enough to give her the least bit of credit.
While gene expressions do not always correspond to gene functions, it should be noted that meiotic genes, especially genes involving recombination, are normally under tight expression control to prevent deleterious consequences of genomic instability.
Cells of JM83 were co-transformed with plasmid pREP4 in order to achieve tight expression regulation and plated on LB/kanamycin/carbenicillin agar plates.
This approach culminated in the development of the uracil-regulatable urg1 promoter system, which allows tight expression control of ectopic genes with otherwise minimal side effects on genome-wide gene expression.
While some genes' mRNA levels are highly variable across many conditions, some show very tight expression patterns with very little variation.
The tight expression regulation and spatial distribution of S6 is indicative of an important cellular function that is likely restricted to sporozoites in the mosquito vector.
The stochastic analysis reveals the importance of both the mechanisms of regulation for tight expression of genes in the GAL network.
However, the TRE-tight promoter showed a significantly tighter expression with minimal background, and still maintained high induction levels.
