Because ribosomes are necessary for the expression of all protein-coding genes, they are highly expressed in replicating cells.
Corcoran, K.A. & Quirk, G.J. Activity in prelimbic cortex is necessary for the expression of learned, but not innate, fears.
orf3 and orf4 were not necessary for the expression of active enzyme in E. coli.
Makela, M.J. et al. IL-10 is necessary for the expression of airway hyperresponsiveness but not pulmonary inflammation after allergic sensitization.
We have previously demonstrated that depletion of glutathione in mesencephalic cultures results in cell death and that the presence of glia is necessary for the expression of toxicity.
Thus, it is possible that subtle dysfunction arising from multiple cell types is necessary for the expression of certain ataxia syndromes.
These results confirm the gonads as the main source of androgens in this species and show that androgens are necessary for the expression of reproductive behaviors.
Here, using a combination of genomic and in vitro approaches, we demonstrate that curaxins strongly affect spatial genome organization and compromise enhancer-promoter communication, which is necessary for the expression of several oncogenes, including MYC.
The differences in sequence are recognized by specific proteins called transcription factors, which are necessary for the expression of particular types of genes.
βCD in the crystal lattice seems to act as a medium allowing the cis to trans isomerisation of ASA, a volume-demanding process necessary for the expression of photochromism in this class of molecules.
These pictures and drawings (called pictographs) are usually considered to be a forerunner of true writing and are characterized by stereotyped execution and by omission of all details not necessary for the expression of the communication.
