The Irish Famine (or ‘Great Potato Famine’ if you live outside the Emerald Isle) killed one million people and forced another million to leave the country between 1845 and 1852. It was caused by a blight on the country’s main food stock- the Irish ‘Lumper’ potato. Now, researchers have identified the genome of the blight…
Since our early steps in Science we have been told that every cell in our body has the exact same genetic information (minus one or two alterations). Therefore, the great variety of cells in our body comes from gene expression – each cell must express one set of genes and repress another set to function…
Genomic Science has come a long way since the early days of Sanger sequencing in the 1970’s. Today, there are jazzy new sequencing technologies that include fragment analysis, epigenetic sequencing, RNA/transcriptome sequencing and Next Generation Sequencing (NGS). Increasingly these technologies are becoming more accessible, but they still require highly specialized (read: expensive) equipment. Unless your…
Welcome to the magical world of systematics! Looking for a way to produce a phylogenetic tree that’s a step above the default options, time efficient, not too program heavy and avoids using command line programs? Although there are more rigorous analyses that strict systematists perform, for your purposes, the following should suffice. 1. Data selection…
There is no such thing as “junk” DNA Until recently, vast areas of the genome had been denounced as “junk” DNA, because they do not encode proteins. However, it has become clear that these regions have a large diversity of other functions, from transcriptional and translational regulation to the protection of genes and genome integrity….
The Rise and Fall of the 454 Sequencer The GS20 454 sequencer, released in 2005, was the first next-generation DNA sequencer to hit the market, and its feats quickly dazzled the scientific community. As new sequencing platforms proliferated, however, many researchers opted for less expensive options and 454 market share fell. About a year ago,…
