Question

In vitro, clonal propagation in plants is characterized by

• A. Electrophoresis and HPLC
• B. Microscopy
• C. Northern blotting
• D. PCR and RAPD

Answer 1

The correct option is D

PCR and RAPD

The correct option is D.

Explanation for the correct option:

Option D:

1. Clonal propagation is a method to replicate genetically identical copies of a plant.
2. PCR stands for Polymer chain reaction is the method by which multiple copies of DNA can be formed.
3. RAPD stands for Random amplified polymorphic DNA is a PCR-based technique that can be used to identify the genetic changes in desired DNA samples of a plant.

Explanation for the incorrect options:

Option A:

Electrophoresis and HPLC are the techniques used to test the hemoglobin level in blood.

Option B:

Microscopy is a method to diagnose pulmonary tuberculosis.

Option C:

Northern blotting is a technique used to transfer isolated RNA to a membrane.

Final answer: In vitro, clonal propagation is characterized by PCR and RAPD.
