Whole Genome Sequencing

Save

Whole Genome Sequencing (WGS) is a revolutionary technique that determines the sequence of nucleotide base pairs that make up an organism's entire genome, including its DNA and mitochondrial DNA. It involves sequencing all of an organism's chromosomal DNA as well as extrachromosomal DNA, including both nuclear and organelle genomes.

How is Whole Genome Sequencing Performed?

WGS is performed using a variety of technologies, including Sanger sequencing, Ion Torrent Personal Genome Machine (PGM), and Illumina HiSeq. The process involves the following steps:

  • Sample Preparation: DNA is extracted from the organism and fragmented into small pieces.
  • Library Preparation: Adapters are added to the ends of the DNA fragments to make them compatible with the sequencing platform.
  • Sequencing: The DNA fragments are sequenced using a high-throughput sequencing platform.
  • Assembly: The sequenced fragments are assembled into a contiguous sequence using bioinformatics tools.
  • Analysis: The assembled sequence is analyzed to identify genes, variations, and other genomic features.

Why is Whole Genome Sequencing Important?

WGS has numerous applications in various fields, including:
