By Laura Elnitski, Helen Piontkivska, Lonnie R. Welch

Mapping the genomic landscapes is likely one of the most enjoyable frontiers of technology. we've the chance to opposite engineer the blueprints and the keep watch over structures of residing organisms. Computational instruments are key enablers within the interpreting procedure. This ebook offers an in-depth presentation of a few of the $64000 computational biology ways to genomic series research. the 1st portion of the e-book discusses tools for locating styles in DNA and RNA. this is often by way of the second one part that displays on tools in numerous methods, together with functionality, utilization and paradigms
