PPT-Genome sequencing and assembly

MayoUIUC Summer C ourse in Computational Biology Session Outline Genome sequencing Schematic overview of genome assembly a DNA is collected from the biological sample and sequenced b The output from the sequencer consists of many billions of short unordered DNA fragments from random positions in the genome c The short fragments are compared with each other to discover how they overlap d The overlap relationships are captured in a large assembly graph shown as nodes representing . sequencing . for . identification,. detection, . and control of .

Your genome is the information needed to build the human body and keep it health . Knowing how many genes determine a phenotype (Mendelian and/or QTL analysis), and where the genes are located (linkage mapping) is a first step in understanding the genetic basis of a phenotype . A second step is determining the sequence of the gene (or genes). and Accurate Assembly Polishing Algorithm. Can Firtina. 1. , Jeremie S. Kim. 1,2. , Mohammed Alser. 1. , . Damla. . Senol.
