AIIMS 2019 Botany Proteins MCQ Question

Type: MCQ-conceptual-Medium-Class 12
  1. Match the column-I and column-II Column-I (i) Viroid (ii) Cell (iii) Virus (iv) Triple helical
A

a - iv - Q, b - iii - P, c - ii - S, d - i - R

B

a - i - Q, b - ii - P, c - iii - S, d - iv - R

C

a - i - Q, b - iii - P, c - ii - S, d - iv - R

D

a - iv - Q, b - ii - P, c - iii - S, d - i - R

Correct Answer

Option C

Detailed Explanation

Option C is correct because it accurately matches each item in Column-I with its corresponding characteristic in Column-II: Viroids (i) are known for their RNA structure, which is often circular and can be associated with diseases in plants (Q); viruses (iii) are acellular infectious agents that require a host to replicate (P); cells (ii) are the basic structural and functional units of life (S); and triple helical refers to the structure of collagen, a protein found in connective tissues (R).

Other options are incorrect as they misassign characteristics, such as matching viruses with cellular structures or misrepresenting the nature of viroids and their association with diseases. Understanding these distinctions is crucial for grasping the fundamental differences between cellular and acellular life forms.
