The signal model proposes that all chromatid breaks arise from a single DNA double strand break (dsb) via a recombinational exchange mechanism. Here the prediction that chromatid breaks arise from a single dsb is tested.The genetically engineered Chi

The building of Hierarchical Control Flow Graph (HCFG) Models of queueing systems is described by developing different model elements of queueing subsystems and then combining them into HCFG Models. A brief overview of HCFG Models, which is a new mod

Several DNA sequence elements are thought to stimulate homologous recombination, illegitimate recombination, or both in mammalian cells. Some are implicated by their recurrence around rearrangement breakpoints, others by their effects on recombinatio

Based upon analyses of purified enzyme preparations, T4 bacteriophage-coded ribonucleotide reductase is considered to be relatively insensitive to control by allosteric inhibition. However, two factors suggest that CDP reduction to dCDP is feedback-c

A questionnaire was used to assess nutritional intake, weight status, and dietary practices among 630 U.S. college students. Body mass index (BMI) was calculated using self-reported heights and weights, and nutritional status was assessed via 24-hour

The purpose of this study was to assess racial and gender differences in perceptions of ideal body size among White and Black fourth-grade children.A random sample of 817 children (51.4% female, 51.8% White, and mean age 9 years) participated in a bo

In mammalian cells, chromosomal double-strand breaks are efficiently repaired, yet little is known about the relative contributions of homologous recombination and illegitimate recombination in the repair process. In this study, we used a loss-of-fun

The FLP/FRT site-specific recombination system was established and characterized at the APRT gene in CHO cells. Targeting frequencies with FLP-stimulation were about 1 to 5 X 10(-5), which were 6-22-fold above gene targeting frequencies in the absenc

Data from studies conducted on South Carolina adolescents indicate caloric intake to be less than recommended, intakes of calcium, iron and fiber are also less than recommended. Protein intake and cholesterol intake appears to higher than recommended

The dietary intakes of energy, protein, calcium, and iron of 408 randomly selected nonpregnant, black and white female adolescents were analyzed to determine their pre-pregnancy nutritional status. Pre-pregnancy weight for height was calculated and u
