Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the differences are TRUE between prokaryotic and eukaryotic cells?
A
in prokaryotic cells, DNA lies freely in mesosome while in eukaryotic cells, DNA located in the nucleus.
B
Prokaryotic cells are generally larger in size (10-100 µm) while eukaryotic cells are generally smaller in size (0.5-10 µm).
C
in prokaryotic cells, DNA is circular and not associated with histone protein while in eukaryotic cells, DNA is linear and associated with histone protein.
D
Prokaryotic cells have 9+2 arrangement of microtubule while eukaryotic cells does not have 9+2 arrangement of microtubule.
Explanation: 

Detailed explanation-1: -Eukaryotic DNA is linear, whereas prokaryotic DNA is circular. Eukaryotic DNA contains adenine, thymine, guanine, and cytosine bases, whereas prokaryotic DNA contains uracil, thymine, guanine, and cytosine bases. Prokaryotic DNA is not found in the nucleus, whereas eukaryotic DNA is.
