Point mutations can show three different types of effects:
- Base substitutions can be silent mutations in which the changed codons correspond to the same amino acid.
- Base substitutions can be missense mutations where the changed codon corresponds to a different amino acid.
- Base substitutions can be nonsense mutations in which the altered codon corresponds to the stop signal.
<h3>What are point mutations?</h3>
Point mutations are changes to the N base of DNA or RNA. Point mutations are common, but their effects can be mitigated by gene recovery mechanisms.
The cause of this point mutation is due to 4 factors:
- Errors during DNA replication by mutagens.
- Breaking of oxygen-phosphate bonds.
- Substitution of base pairs.
- Changes in the number of bases.

<span>The statement that best describes an independent variable is B. the variable you can change in an investigation. There can be only one independent variable during an experiment, because if you change more things, you won't know which variable it is that brought about the change. So, there is one variable that you change that doesn't depend on anything else and that you can alter in order to get the results you want.</span>
