Options
- AA - 2, B - 4, C - 3, D - 1
- BA - 4, B - 1, C - 2, D - 3
- CA - 3, B - 2, C - 1, D - 4
- DA - 1, B - 3, C - 4, D - 2
Correct answer
A. A - 2, B - 4, C - 3, D - 1
Step-by-step solution
A - 2: Histone octamer is a positively charged protein complex around which DNA is wrapped in eukaryotic cells. B - 4: The nucleoid is the region in prokaryotes where DNA is organized. C - 3: Euchromatin is loosely packed chromatin that stains lightly and is transcriptionally active. D - 1: Heterochromatin is transcriptionally inactive chromatin that is densely packed and stains dark.
