Scientists from Helicos BioSciences, Ohio University, and Stanford University have published a paper in Science describing the first single-molecule sequencing of a whole genome.
The researchers used a single-molecule sequencing, sequencing-by-synthesis method, developed by Helicos, to sequence the roughly 7,000-nucleotide genome of the M13 virus. In the company’s version of single-molecule sequencing, an approach first proposed in the […]

‘Clover structure’ of Transfer RNA
Transfer RNA (tRNA) is ancient. It is the most direct intermediary between genes and proteins. Like many other RNAs (ribonucleic acids), tRNA aids in translating genes into the chains of amino acids that make up proteins. The fact that tRNA is so central to the task of building proteins probably means […]

US scientists have discovered a possible reason why the flu virus is seasonal and tends to infect people mostly in the winter. It has a jacket that melts in the summer causing the virus to die off, and stays hard in the winter, until it […]
