#Scientists construct first whole genome sequence of bighorn sheep Geneticists at the University of Alberta have constructed the first whole genome sequence of a bighorn sheep in a new study that could have a significant impact on conservation efforts of the species,
To construct a whole genome sequence, the DNA is first run through a sequencer to identify small strings of building blocks, called nucleotides.
The strings of nucleotides are joined then together to produce a complete picture. he process of ordering the nucleotides into a genome is much like assembling a jigsaw puzzle,
which uses an existing genome sequence as a reference point to streamline the process. ere, one starts with the same jigsaw pieces,
and for genome sequencing this usually results in a much more complete picture being put together in less time than de novo assembly.
In this case, the reference used for alignment was the already complete whole genome sequence of a domestic sheep.
Full genome sequences are still relatively rare; for context, only 108 mammals are listed in the National Center for Biotechnology Information database. ntil recently,
