NEETBotanyCell - The Unit of Life
Nuclear Components Characteristics A. Chromatin 1. Stained by basic dyes and composed of nucleoprotein fibers B. Nuclear Envelope 2. Barrier between nucleus and cytoplasm with a perinuclear space C. Nucleolus 3. Allows movement of RNA and proteins between nucleus and cytoplasm D. Nuclear Pores 4. Site for ribosomal RNA synthesis and not membrane-bound
Options
- AA - 1, B - 2, C - 4, D - 3
- BA - 2, B - 3, C - 1, D - 4
- CA - 3, B - 1, C - 2, D - 4
- DA - 4, B - 3, C - 1, D - 2
Correct answer
A. A - 1, B - 2, C - 4, D - 3
Step-by-step solution
Chromatin is the nucleoprotein fiber stained by basic dyes.The nuclear envelope forms a barrier with the perinuclear space.The nucleolus is involved in ribosomal RNA synthesis and is not membrane-bound.Nuclear pores are passages for RNA and protein movement.
