A) DNA is complexed with histones
B) Well developed nucleus absent
C) Mesosome present
D) Mitochondria absent
Correct Answer: A
Solution :
In prokaryotic cell the genetic material is not organised into nucleus and all the membrane bound organelles (mitochondria, chloroplast, Golgi body, endoplasmic reticulum, lysosomes) are absent. The histone proteins are absent and therefore the genetic material is not organised into chromatin. The DNA is bound with some basic proteins to form the prochromosome. Mesosome is formed by invagination of plasma membrane. It may be equivalent to mitochondria as respiratory enzymes occur over it as well as on plasma membrane.
