    Massive parallel sequencing is a very rapid method of sequencing millions of DNA fragments at the same time; it is also called next-generation sequencing (NGS) or second-generation sequencing. 'These technologies use miniaturized and parallelized platforms for sequencing of 1 million to 43 billion short reads (50-400 bases each) per ...

  9. DNA Sequencing

    DNA sequencing is the process of determining the exact sequence of nucleotides within a DNA molecule. This means that by sequencing a stretch of DNA, it will be possible to know the order in which the four nucleotide bases - adenine, guanine, cytosine and thymine - occur within that nucleic acid molecule.
