Question 2 Which type of mutation can be silent, meaning the mutation doesn't lead to a different protein being synthesized.

A point mutation

Explanation:

If a point mutation does not change the amino acid, it's called a SILENT mutation. If a point mutation changes the amino acid to a “stop,” it's called a NONSENSE mutation. Deletion and insertion may cause what's called a FRAMESHIFT, meaning the reading frame changes. I know the answer on my own, but this explaination i found on the web is better than my own
