Mutations are small or large changes in the sequence of DNA bases, and arise at different stages in the cell cycle, most often when DNA is being replicated. Most of the time, there are mechanisms that can repair these errors, but sometimes mutations remain as permanent changes in the DNA. What are the implications of a mutation?
a) Some mutations lead to cancer
b) Some mutations do not have any impact and are called silent mutations
c) Some mutations may lead to a different protein being produced
d) Some mutations may prevent certain proteins from being produced
