Question

Read the following statements carefully:
(A) Ultracentrifugation separates molecules based on their density
(B) Gel electrophoresis separates molecules based on their mobility in an electric field
(C) Gel filtration separates molecules based on their size
(D) NMR separates molecules based on their proton signal
Choose the correct answer from the options given below:

• A. (A), (B) and (D) only
• B. (A), (B) and (C) only
• C. (A), (B), (C) and (D)
• D. (B), (C) and (D) only

Hint:

Gel electrophoresis is for electric mobility, while gel filtration works on molecula size.

Answer 1

The Correct Option is B

Ultracentrifugation separates molecules like proteins and nucleic acids based on density differences. Gel electrophoresis works on molecular mobility in an electric field. Gel filtration separates molecules by size using porous beads.
