Question

Arabidopsis thaliana and Caenorhabditis elegans has one thing common. Which is it?

• A. Both are GM crops.
• B. Both contain introduced foreign genes.
• C. Both are worms.
• D. Both have been the first ones in 'Human Genome Project', whose genes have been fully sequenced.

Answer 1

The correct option is D Both have been the first ones in 'Human Genome Project', whose genes have been fully sequenced.

Arabidopsis thaliana is a small flowering edible plant native to Eurasia. It was the first plant to have its genome sequenced for understanding the molecular biology of many plant traits.

Caenorhabditis elegans is a free-living (not parasitic), transparent nematode (roundworm) that lives in temperate soil environments. It was the first multicellular organism to have its whole genome sequenced, and as of 2012, the only organism to have its connectome completed.
