Question

DNA copying mechanisms create .......... which is useful for ensuring the survival of the species.

• A. Recombination
• B. Variation
• C. Mutation
• D. All of the above

Answer 1

The correct option is B Variation

• DNA copying mechanisms create variations which are useful for ensuring the survival of the species.
• Evolutionary change by natural selection (or genetic drift) requires variation in DNA.
• Sometimes, DNA-copying mechanisms may insert the wrong base. This also will result in variations.
