Whole genome sequencing

A genome is the entire DNA sequence of an organism. The DNA contains the instructions for how a living organism is formed. Whole genome sequencing WGS is a next generation sequencing application that determines the entire DNA sequence all at once. The alternative to WGS is targeted next generation sequencing, which sequences part of the genome. The first genome sequenced was the genome of a bacterium that causes bacterial influenza, Haemophilus influenzae. This bacterial genome was sequenced in , using shotgun sequencing whereby you randomly sequence short fragments of the genome and then reassemble using bioinformatics tools [ 1 ].

Whole genome sequencing

Metrics details. Haemophilus influenzae is an important human commensal pathogen associated with significant levels of disease. High-throughput DNA sequencing was used to investigate differences in genome content within this species. Genomic DNA sequence was obtained from 85 strains of H. When compared by Mauve alignment these indicated groupings of H.

Whole genome sequencing WGS , also known as full genome sequencing , complete genome sequencing , or entire genome sequencing , is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. Whole genome sequencing has largely been used as a research tool, but was being introduced to clinics in Whole genome sequencing should not be confused with DNA profiling , which only determines the likelihood that genetic material came from a particular individual or group, and does not contain additional information on genetic relationships, origin or susceptibility to specific diseases. As of there were no complete genomes for any mammals , including humans. The DNA sequencing methods used in the s and s were manual, for example Maxam-Gilbert sequencing and Sanger sequencing. Several whole bacteriophage and animal viral genomes were sequenced by these techniques, but the shift to more rapid, automated sequencing methods in the s facilitated the sequencing of the larger bacterial and eukaryotic genomes. The first organism to have its entire genome sequenced was Haemophilus influenzae in

The human genome project is entering its decisive final phase, in which the genome sequence will be determined in large-scale efforts in multiple laboratories worldwide. A number of sequencing groups are in the process of scaling up their throughput; over the next few years they will need to attain a collective capacity approaching half a gigabase per year to complete the 3-Gb genome sequence by the target date of At present, all contributing groups are using a clone-by-clone approach, in which mapped bacterial clones typically 40— kb in size from known chromosomal locations are sequenced to completion. Among other advantages, this permits a variety of alternative sequencing strategies and methods to be explored independently without redundancy of effort. Although it is not too late to consider implementing a different approach, any such approach must have as high a probability of success as the current one and offer significant advantages such as decreased cost.

We describe a variation on hierarchical sequencing with two crucial differences: 1 we select a clone library from the genome randomly rather than as a tiling path and 2 we sample clones from the genome at high coverage and reads from the clones at low coverage. Our assembly methodology is based on first ordering the clones and subsequently performing read assembly in three stages: 1 local assemblies of regions significantly smaller than a clone size, 2 clone-sized assemblies of the results of stage 1, and 3 chromosome-sized assemblies. By aggressively localizing the assembly problem during the first stage, our method succeeds in assembling short, unpaired reads sampled from repetitive genomes. We tested our assembler using simulated reads from D. Tested on D.

In genetics , shotgun sequencing is a method used for sequencing random DNA strands.

Six out of ten completely sequenced bacterial genomes are pathogenic or opportunistic bacteria.
