Caenorhabditis elegans
|
Detailed explanation-1: -Besides providing clues to understanding human biology, sequencing of many non-human model organisms, such as bacteria, yeast, Caenorhabditis elegans (a free living non-pathogenic nematode), Drosophila (the fruit fly), plants (rice and Arabidopsis), etc. have also been done. Q.
Detailed explanation-2: -The C. elegans genome project began over 10 years ago and is a collabo-rative effort between two laboratories (St. Louis, MO, USA, and Cambridge, UK), with the ultimate aim of mapping and sequencing the whole of the 100-Mb genome.
Detailed explanation-3: -As a key component of the HGP, it was wisely decided to sequence the smaller genomes of significant experimental model organisms such as yeast, a small flowering plant (Arabidopsis thaliana), worm and fruit fly before taking on the far more challenging human genome.
Detailed explanation-4: -John Sulston and Bob Waterston led the way for the Human Genome Project after they successfully sequenced the genome of the nematode worm, Caenorhabditis elegans, the first animal to be sequenced.
Detailed explanation-5: -In December 1998, the first genome sequence of a multicellular organism, the roundworm Caenorhabditis elegans, was completed.
