Given below is the diagrammatic representation of a nucleus. Match the labeled parts (A, B, C, D) in List I with their corresponding characteristics or functions in List II. List I List II A Label A 1 Network of nucleoprotein fibres containing DNA and basic proteins B Label B 2 Site for active ribosomal RNA synthesis C Label C 3 Often bears ribosomes and is continuous with the endoplasmic reticulum D Label D 4 Passag
Options
- AA-2, B-1, C-4, D-3
- BA-1, B-2, C-3, D-4
- CA-2, B-4, C-1, D-3
- DA-4, B-1, C-3, D-2
Correct answer
A. A-2, B-1, C-4, D-3
Step-by-step solution
Based on the provided diagrammatic representation of a nucleus: Label A represents the nucleolus, which is a dense, spherical structure present in the nucleoplasm. It is the site for active ribosomal RNA (rRNA) synthesis. Thus, A matches with 2. Label B represents chromatin, which is a network of nucleoprotein fibres containing DNA and basic proteins (histones). Thus, B matches with 1. Label C represents a nuclear pore. These pores are formed by the fusion of the two nuclear membranes and act as passages for the mo
