How do mutations affect proteins structure and functions ?

Solution

Mutations causes changes in the genetic code, thus the new code produces new proteins. The effects of all mutations will be reflected in protein structure and functions. It can be due to frameshift mutation or point mutation. The addition or deletion or modification of any bases or codons will produce a new protein with altered function.
