Q. No.| 1. | The Human Genome Project was a 13-year project coordinated by the U.S. Department of Energy and the National Institute of Health. |
| 2. | 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 sequenced. |
| 3. | The sequence of chromosome 1 was completed only in May 2016 (this was the last of the 24 human chromosomes – 22 autosomes and X and Y – to be sequenced). |
| 4. | The fragments were sequenced using automated DNA sequencers that worked on the principle of a method developed by Frederick Sanger. |
