Changes in these conditions can change the composition of species that make up the marine community.
The correct answer is: silent mutation
There are a few types of genetic mutation that can change genetic code. Those mutations can be classified:
1. Substitution-only one base is changed
• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon
• Missense mutations-when one nucleotide is substituted and a different codon is formed
• Silent mutations-when a nucleotide is substituted and the same amino acid is produced
2. Insertion- extra base pairs are inserted
3. Deletion- section of DNA is deleted
