B- Enzymes act as catalysts to speed up chemical reactions
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.
