PPT-Introduction to Short Read Sequencing Analysis

Jim Noonan GENE 760 Sequence read lengths remain limiting For most applications reads are aligned to a reference genome Short reads contain inherently limited information De novo assembly of short reads is difficult. Mayo/UIUC 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 . Craig A. . Praul.
