PPT-Next generation sequencing: an overview

A I Bhat Indian Institute of Spices Research Calicut DNA sequencing Chain termination method Sangers et a l 1977 In this method the sequence of a single stranded DNA molecule is determined by enzymatic synthesis of complementary polynucleotide chains these chains terminating at specific nucleotide positions. 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 .
