What can cause a frameshift mutation? An inversion An insertion or deletion A silent mutation A substitution

## Step 1<br />A frameshift mutation is a type of mutation that occurs when the number of nucleotides in a DNA sequence is altered, which changes the way the sequence is read. This can happen due to an insertion or deletion of nucleotides.<br /><br />## Step 2<br />An inversion is a type of mutation where a segment of DNA is reversed within the chromosome. This does not cause a frameshift mutation.<br /><br />## Step 3<br />A silent mutation is a type of mutation where a change in the DNA sequence does not affect the protein sequence. This does not cause a frameshift mutation.<br /><br />## Step 4<br />A substitution is a type of mutation where one nucleotide is replaced by another. This does not cause a frameshift mutation.
