This week we have selected the term “gene mutation” with reference to the developments in the prevention of Alzheimer’s disease. (Read article in The New York Times)
Definition: a genetic change at the level of the genes; a change in the nitrogenous base sequences

Gene mutations based on the mechanism that caused it are as follows:
• base pair substitution
• frame shift mutation
