Question

Which one of the following is a prokaryote ?

• A. Entamoeba
• B. Saccharomyces
• C. Paramecium
• D. E.coli

Answer 1

The Correct Option is D

E. coli is Gram negative, rod shaped bacterium belonging to the kingdom of prokaryotes, i.e. Monera.Monera includes all prokaryotes, viz., mycoplasma, bacteria, actinomycetes (mycelial bacteria) and photosynthetic cyanobacteria. Plastids, mitochondria, endoplasmic reticulum, Golgi bodies, lysosomes and other membrane bound organelles are absent. The genetic material is naked circular DNA, neither enclosed by nuclear envelope nor complexed with proteins and without formation of well defined chromosomes. It is called nucleoid or genophore.

Answer 2

Ans. E. coli is the prokaryote organism of all.

• Prokaryotes' genetic material is located in the cytoplasm and they lack a nuclear membrane.
• Organelles attached to membranes are absent in these species.
• They have 70s-era ribosomes.
• Eukaryotes include organelles, 80s ribosomes, and a nucleus that is encircled by a membrane.
• Gram-negative, coliform bacteria are E. coli. 
• A prokaryotic entity is a bacterium.
• E. coli is therefore not a eukaryote but a prokaryote.

E. coli

• Warm-blooded animals' intestines contain the bacterium E. coli. 
• It is a gram-negative, rod-shaped bacterium. 
• The human digestive tract benefits from this bacterium, however, some strains can also lead to food poisoning and other digestive issues when consumed. 
• Additionally, it results in urinary tract infections, which have serious health consequences. 
• E. coli, which has several types, can cause food poisoning and diarrhea. 
• In the worst-case circumstances, renal failure might potentially happen.
