Differentiate between point mutation and frameshift mutations.

Explanation

### Step-by-Step Text Solution

**Step 1: Definition of Point Mutation**
- Point mutation is defined as a mutation that involves a change in a single nucleotide in the DNA sequence. This alteration can occur through substitution, where one nucleotide is replaced by another.

**Step 2: Definition of Frameshift Mutation**
- Frameshift mutation, on the other hand, involves the insertion or deletion of nucleotides in the DNA sequence. This results in a shift of the reading frame of the genetic code, which can significantly alter the entire protein that is produced.
