V.Question
Single Nucleotide Polymorphism (SNP)
SNP:
A single nucleotide (A, T, C or G)
mutation
Use:
• genetic and genome mapping,
• Association studies,
• Genetic diversity analysis, and
• Tagging important genes
Approach:
•
SNP discovery from PCR
• SNP discovery from High throughput Next generation sequencing (NGS) –
RNA-Seq, RAD-Seq, GBS etc.

harma/snips/)
SNP Discovery Tool
There are dozens of tools for SNP discovery. We will talk below two:
• BioEdit
Download: http://www.mbio.ncsu.edu/bioedit/page2.html
Manual: http://www.mbio.ncsu.edu/BioEdit/BioDoc.pdf
• DNASTAR Lasergene Genomics Suite
Download free TRY IT version : http://www.dnastar.com/tproducts-dnastar-lasergene-genomics.aspx and all use manuals can
also be downloaded or viewed from the web site.
SNP Genotyping
Single SNP genotyping assay:
• Taqman – Life Technologies
http://www.vetmed.ucdavis.edu/vme/taqmanservice/pdfs/SNP_Genotypin
g.pdf
• KASP genotyping - LGC Genomics
http://www.lgcgenomics.com/genotyping/kasp-genotypingchemistry/how-does-kasp-work/
Multiple SNP genotyping:
• SNP chip – Illumina
• Multiplex – Sequenom
SNP genotyping by next generation sequencing
• Genotyping by sequencing (GBS)
(http://cbsu.tc.cornell.edu/lab/doc/GBS_Method_Overview1.pdf)
• Restriction site associated DNA sequencing (RADseq)
(http://bfg.oxfordjournals.org/content/9/5-6/416.full.pdf+html)
