Question

DNA is unique among molecules in that it can

• A. Form multipolymer complexes
• B. Come apart and re-form
• C. Withstand very high temperatures
• D. Replicate itself

Answer 1

The correct option is D Replicate itself

DNA which serves as the genetic material for several organisms and contains genetic information in the form of genes has several features like:

i) It is a double helix structure which makes it less reactive.

ii) It is least affected by the change in surroundings.

iii) It has the ability to replicate itself and makes an exact copy.

iv) DNA gets denatured at very high temperatures due to the breaking of the hydrogen bonds.

So the correct option is 'Replicate itself'.
