A conservative substitution is when

• A new amino acid is coded for which has very different properties and the protein does not function.

• A new amino acid is coded for which has very different properties and the protein functions better.

• A new amino acid is coded for which has very similar properties and the protein functions normally.

• A frameshift mutation must have occurred.

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence
