A scientist is studying gene expression in a prokaryote which of the following organisms could be the scientist be studying

Bacillus subtitles , a bacterium
Leucobryon glaucoma , a Moss
Lycoperdon pyriforme , a fungus
Caenorhabditis elegans, a roundworm

 

Answer:

Bacillus subtilis, a bacterium

Explanation:

In the given choices above, Bacillus subtilis is the only prokaryotic organism; moss, fungus and roundworm are all eukaryotic organism.

Prokaryotes/prokaryotic cells lacks membrane bound organelles such as nucleus, endoplasmic reticulum, mitochondria,Golgi apparatus, etc., and they usually have circular DNA. Prokaryotes are only one-celled organism, and its major member is bacteria.

Eurkaryotes, on the other hand, can be single-celled or multicellular, like the other three you mentioned above. Humans, animals, and plants are eukaryotes.

PS:

Its not Bacillus subtitles, its Bacillus subtilis.
