2. A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed. However, some mutations are spontaneous. Do the necessary research and discuss:

(i) What do we mean by mutations being spontaneous. (1)

(ii) Further discuss how the following can lead to mistakes at the time of DNA

replication (a) A base analogy (b) Nitric acid (c) UV light. (9)
