The table below shows sequence of nucleotides on a chromosome before and after mutation.The type of mutation in the given case is
Correct answer: C. Substitution
- A. Deletion
- B. Inversion
- C. Substitution
- D. Transposition
Explanation
The mutation is a Substitution because one or more nucleotides have been replaced by a different nucleotide as shown in figure.If we assume the change is T at position 4 to A at position 4, and A at position 5 to T at position 5, it's two substitutions. So option B is correct. Deletion, inversion or transposition is not shown in the given figure.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
