These short sequences — usually about 500 nucleotides in length — are termed expressed sequence tags.

The blade, he found, is an enzyme that always cuts the viral DNA code where it finds a particular short sequence of nucleotides.

Another breakthrough came a few years later with the discovery of «microsatellites», short sequences of two to four nucleotides.

Next - gen sequencing is particularly useful for analyzing highly fragmented DNA, adds Eske Willerslev, a geneticist at the University of Copenhagen's Natural History Museum of Denmark, because it can capture the sequences of exceedingly short stretches of nucleotides.

Their work arose out of a discovery in the late 1980s of neighboring bacterial DNA segments consisting of repeating nucleotide sequences, which flank short segments.

MNLPs join the list of sequence variations that have been discovered in recent years, including SNPs (single nucleotide polymorphisms), INDELs (insertions or deletions of various lengths), and STRs (short tandem repeats).

This is a highly parallel sequencing approach that involves synthesizing short regions of identical DNA fragments on magnetic beads, packing millions of them into a chamber and then extending each of those molecules while detecting the addition of fluorescently labeled DNA building blocks or nucleotides.
