Mutations
DNA/Gene muations
| Question | Answer |
|---|---|
| substitution | type of mutation where one base is swapped with another base |
| insertion | type of mutation where one (or more) bases are added |
| deletion | type of mutation where one (or more) bases are removed |
| frameshift mutation | when bases are inserted or deleted, which changes the codons and affects all the amino acids that come after the change |
| silent mutation | when one base is substituted and it does not change the amino acid, so the protein stays the same |
| missense mutation | when one base is substituted, changing one codon so it codes for a different amino acid |
| nonsense mutation | when one base is substituted, changing a codon into a stop codon |
| mutation | a change in the DNA sequence of an organism |
| mutagen | something that causes a mutation in DNA (such as radiation, chemicals, or UV light) |
| beneficial mutation | have a positive effect on the organism |
| harmful mutation | have a negative effect on the organism |
| neutral mutation | have neither a positive or negative effect on the organism |
