Verified By Collegedunia
The Correct Option is A
Solution and Explanation
To create a recombinant DNA molecule, both the vector DNA and the source DNA need to be cut with the same restriction enzyme. This creates complementary sticky ends that can anneal (base pair) with each other, allowing the source DNA to be inserted into the vector. If different restriction enzymes are used, the sticky ends will not be complementary, and the recombinant DNA molecule cannot be formed.

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]
