A recent article titled Natural gas: A modern fuel millions of years in the making reported that the refined gas used in barbecue grills marks the last step in a process that began more than 500 million years ago. 1. But that's not so. Natural gas can be produced by adding heat and water to brown coal.
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule.It includes any method or technology that is used to determine the order of the four basesâ adenine, guanine, cytosine, and thymine âin a strand of DNA.The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery.NA sequencing is the determination of the physical order of these bases in a molecule of DNA. However, there are many other bases that may be present in a molecule. In some viruses (specifically, bacteriophage), cytosine may be replaced by hydroxy methyl or hydroxy methyl glucose cytosine.
Shotgun sequencing: An approach used to decode a genome by shredding (shotgunning) it into smaller fragments of DNA which can then be individually sequenced.
