Method For Identification Of Origins Of Replication And Genes Regulated By Dnaa In Bacteria, Olga G. Troyanskaya

Honors Theses

The study is focused on developing computer programs to identify origin of DNA replication based on analysis of total bacterial genomes, scoring regions for number of DnaA binding sites, AT content, DNA adenine methylase boxes, and integration host factors binding sites. The programs were tested on cyanobacterium Synechocystis, and several potential origins were identified. However, no one definite region could be located. Currently, software is being developed to analyze common motifs around the origins of all bacteria with known origins. Genes whose transcription could be regulated by DnaA were identified by searching for DnaA boxes preceding promoter regions.

Establishing A Link Between Mapk Pathways And Hormones Signal Transduction In Plants, Marc Meulener

Honors Theses

Mitogen Activated Protein Kinase (MAPK) pathways are ubiquitous among eukaryotes, and are involved in the transduction of various extracellular signals. In mammals, three MAPK pathways have been identified, two of these respond to stress, and one can stimulate growth and differentiation. MAPKs have also been found in plants, and it has been suggested that a MAPK pathway may be involved in the signal transduction of auxin and cytokinin, two plant hormones that stimulate growth and differentiation. However, at this time, there is no conclusive evidence supporting this hypothesis. By studying the effect ofMAPKK's of both plant and animal origin in …

The Effect Of Different Warm-Downs On Heart Rate Recovery And Muscular Lactic Acid Removal, Alison Jean Perkins

Honors Theses

Competitive swimmers and coaches have had varying ideas about what exercises constitute an appropriate warm-down. However, there is much agreement about what a warm-down should achieve. A good warm-down should do three things. First, a warm-down should be successful in returning the swimmer's elevated heart rate to the resting heart rate level in a relatively short period of time. Second, the warm-down should flush lactic acid out of the muscles as quickly as possible, and restore blood lactate to baseline levels. Finally the warm-down should contribute to improved athletic performances.

In this experiment, it was expected that a decreasing intensity …
