Question

Match List - I with List - II.

List - I	List - II
A. ELISA	I. Visualization of cells
B. RIA	II. Proteins identification
C. Centrifugation	III. Hormone detection
D. Microscopy	IV. Isolation of organelles

Choose the correct answer from the options given below:

• A. A-I, B-II, C-III, D-IV \
• B. A-IV, B-III, C-II, D-I \
• C. A-II, B-III, C-IV, D-I \
• D. A-III, B-II, C-IV, D-I

Hint:

Microscopy is straightforwardly connected to viewing/visualization of cells (D-I). Centrifugation separates parts by spinning, hence isolating organelles (C-IV).

Answer 1

The Correct Option is C

Step 1: Concept Biochemical assays and biophysical methodologies are tailored to distinct analytical purposes, spanning molecular detection, mass separation, or structural rendering.

Step 2: Meaning * ELISA: Enzyme-Linked Immunosorbent Assay. * RIA: Radioimmunoassay.

Step 3: Analysis * ELISA (A) is widely applied for antigen/protein detection and quantification via antibody-linked color changes $\rightarrow$ (A-II). * RIA (B) utilizes radiolabeled molecules to target and evaluate subtle biochemicals, historically crucial for hormone level quantification $\rightarrow$ (B-III). * Centrifugation (C) uses centrifugal fields to separate components by mass and density, facilitating cellular fractionation $\rightarrow$ (C-IV). * Microscopy (D) focuses visible light or electrons to enlarge tiny entities for optical monitoring $\rightarrow$ (D-I).

Step 4: Conclusion This leads to the configuration A-II, B-III, C-IV, D-I, which aligns perfectly with option C. Final Answer: (C)
