Question
Protistan genome has
Options
A.membrane bound nucleoproteins embedded in cytoplasm
B.free nucleic acid aggregats
C.gene containing nucleoproteins condensed together in loose mass
D.nucleoprotein in direct contact with cell substance
Solution
Eukaryotic (eg, protistan) genome is organised in the form of nucleus. It is differentiated into nuclear envelope, chromatin, one or more nucleoli and nucleoplasm. Nuclear DNA is linear, associated with histone proteins. A small quantity of DNA is also found in the plastids and mitochondria. In contrast, prokaryotic (bacterial) DNA is circular and lies freely in the cytoplasm.
