1.Select the incorrect statementi. Cell membrane enveloped all eukaryotic cells & visible under EM with trilaminarstructure.ii. Shape, structure, and position of the nucleus vary between cell types & can bevisibled only from EM.iii. Nucleoplasm composed of chromatin (DNA) complex with protein (histone) ,stainedin blue with hematoxylin or other basic dyes.iv. Heterochromatin is condensed DNA/ chromatin in the nucleoplasm & electrondense area under EM.v. Euchromatin is uncoiled DNA in the nucleoplasm & electron lucent areas under EM
