Answer: 
1. Substitution 
2. Insertion and deletion 
3. Amino acids can have more than one codon that signals for it. Due to this, some substitutions don’t affect the protein at all. 
Explanation: 
1. Substitution sometimes isn’t as impactful. It can result in the same amino acid to be signaled as the original one since amino acids can have more than one codon signaling for it.
2. Insertion and deletion are also known as frameshift mutations. This is because they shift the codon spots by adding or deleting a nucleotide.

Your body constantly produces new cells. Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don't follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells.
