- Assertion: The true nucleus is generally absent in E. coli and other prokaryotes
. Assertion: The true nucleus is generally absent in E. coli and other prokaryotes
Reason: An undifferentiated, unorganised fibrillar nucleus withour any limiting membrane is observed in prokaryotic cells
Solution: E. coli is a well studied prokaryotic cell. Prokaryotic cell lacks true nucleus and membrane bound organelles like mitochondria. Choloroplast, E.R. Golgi body etc. There are an undifferentiated, unorganised fibrillar nucleus without any nuclear membrane in prokaryotic cells. The genetic material of prokaryotic cell is dispersed in cytoplasm and is known as nucleoid.
