Question

Many non–humans model organisms have also been sequenced along with the human genome, these are

• A. bacteria and yeast
• B. plants (rice and Arabidopsis)
• C. Caenorhabditis elegans (nematode) and fruitfly
• D. all of the above

Answer 1

The correct option is D all of the above

Genome sequencing is also referred to as the DNA sequencing. Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence of DNA can reveal lots of genetic information, helping identify genes that code for proteins, regulatory instructions that can instruct genes to turn on or off, as well as mutations that can cause disease. Human genome project (HGP) is one such achievement of DNA sequencing of the whole human genome. 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.
