Correct option:(D) Salmonella typhi
Solution:
- Model organisms are used in genome sequencing and mapping techniques.
- These are used to understand biological processes.
- Various organisms that are used in genome sequencing and mapping techniques are Escherichia coli, Yeast (Saccharomyces cerevisiae), Fruit fly (Drosophila melanogaster), Mouse (Mus musculus), Nematode worm (Caenorhabditis elegans).
- Escherichia coli is easy and inexpensive to grow in laboratory.
- It is widely used prokaryote in research.
- Drosophila has small genome and short reproduction cycle.
- So, new flies are very easy and quick to make for genetic research.
- Mouse genome is very similar to the human genome.
- Hence, it is used to study human diseases.
