18 A Annotation of the Listeria monocytogenes Genome from DNA Coordinates 1450..2513 and 5886..7337 Alycia A. Davenport*, Bridget K. Miller*, and Kathryn S. Hoppe Kendall High School and the Western New York Genetics in Research and Health Care Partnership Abstract LM5923_0009: The ini tial propo sed product of thi s gene by GENI-ACT was Listeria monocytogenesisprin cipally found in pathogenic ca ses offood Modules ofthe GEN I-ACT (http://w w w .geni-act.org/) were used to hypothetical protein. The top BL AST hits for thi s gene were, poisoning. This organism which cause s Listeriosis, is one of the complete Listeria monocytogene s genome annotation. The however, Rhamnulokinase . The BL AS T hits had signi fi cant and leading causes of death offoodborne pathogens. The bacterium can modules are described below: spr ead from the si te of infe ction in the intestines to the nervous system scor e s and E-value s. The cor r ec t annotation being Modules Activities Questions Investigated Rhamnulokinase isalso suppor ted byTIGRFAM and PFA M hitsfor to the placenta in pregnantindividuals. The purpose of this study was Module 1- Basic Information DNA Coordinates and What is the sequence of my to identify and explain different coding regions of the genome of Module Sequence, Protein Sequence gene and protein?
