Because deism asserts God without accepting claims of divine revelation, it appeals to people from both ends of the religious spectrum.

Because St. Louis was geographically isolated from both the dominating teams and the major sports media ( newspapers ) of the era ... all centered in and focused on the East ... Cochems ' groundbreaking offensive strategy was not picked up by the major teams.

Because of its strategic location it is in both the Russian and American spheres of influence.

Because Formalin-fixed, paraffin-embedded ( FFPE ) tissues may be stored indefinitely at room temperature, and nucleic acids ( both DNA and RNA ) may be recovered from them decades after fixation, FFPE tissues are an important resource for historical studies in medicine.

Because of its long seacoast, Italy also has a large number of harbors for the transportation of both goods and passengers.

Because most such alleles are rare in populations, it is unlikely that two unrelated marriage partners will both be heterozygous carriers.

Because of this, a civil libertarian outlook is compatible with many other political philosophies, and civil libertarianism is found on both the right and left in modern politics.

Because of its importance as a symbol of indigenous culture, its gluten-free palatability, easy to cook, and its protein particularly well suited to human nutritional needs, interest in grain amaranth ( especially A. cruentus and A. hypochondriacus ) revived in the 1970s.

Because this protein gp120 is necessary for HIV to attach, it does not change across different strains and is a point of vulnerability across the entire range of the HIV variant population.

Because of this breed ’ s increased muscle yield a diet containing higher protein is required to compensate for the altered mode of weight gain.

Because most malignant cells rely on the activity of the protein telomerase for their immortality, it has been proposed that a drug that inactivates telomerase might be effective against a broad spectrum of malignancies.

Because secondary structures are local, many regions of different secondary structure can be present in the same protein molecule.

Because protein kinases have profound effects on a cell, their activity is highly regulated.

Because of this low specificity, new serological tests have been developed, which test for the presence of the anti-citrullinated protein antibodies ( ACPAs ) or anti-CCP.

Because they tend to have strong flavors and are used in small quantities, spices tend to add few calories to food, even though many spices, especially those made from seeds, contain high portions of fat, protein, and carbohydrate by weight.

Because protein phosphorylation is one of the most-studied protein modifications, many " proteomic " efforts are geared to determining the set of phosphorylated proteins in a particular cell or tissue-type under particular circumstances.

Because CD14 lacks a cytoplasmic domain it was clear that at least one other protein was required for the endotoxin response.

Because the symptoms are caused by failure to make protein, they emerge only after a variable delay from a few hours to a full day after exposure.

Because ricin is a protein, it can be genetically linked to a monoclonal antibody to target malignant cells recognized by the antibody.

Because of the necessary low fat and moisture content, jerky is high in protein.

Because most eukaryotic genes contain introns which are present in the genome but not in the mature mRNA, the cDNA generated from a RT-PCR reaction is the exact ( without regard to the error prone nature of reverse transcriptases ) DNA sequence which would be directly translated into protein after transcription.

Because of its relatively low cost, high protein content, and long shelf life, TVP is often used in prisons and schools, as well as for disaster preparedness.

Because nectar's protein content alone is insufficient for oogenesis ( egg production ) one or more blood meals is needed by the female.

Because red blood cells ( erythrocytes ) have a higher concentration of protein ( e. g., hemoglobin ) than serum, serum has a higher water content and consequently more dissolved glucose than does whole blood.

Because protein structure is closely linked with protein function, the structural genomics has the potential to inform knowledge of protein function.

Because actin monomers must be recycled to sustain high rates of actin-based motility during chemotaxis, cell signalling is believed to activate cofilin, the actin-filament depolymerizing protein which, as stated, binds to ADP-rich actin subunits nearest the filament's pointed-end and promotes filament fragmentation, with concomitant depolymerization in order to liberate actin monomers.

Because of its short genome and its simple composition — only RNA and a non-enveloped icosahedral protein coat that encapsulates it — poliovirus is widely regarded as the simplest significant virus.

Because protein complexes are responsible for most biological functions, genetic interactions are a powerful tool.
