| Question | Answer |
| What Is Meant By A Silent Mutation? | When the mutation leads to the same amino acid being produced |
| What Is Meant By A Neutral Mutation? | An amino acid with similar properties is used so the protein still fuctions correctly |
| What Is Meant By A Nonsense Mutation? | When a premature stop codon has been inserted |
| What Is Meant By A Missense Mutation? | When one amino acid has been substitued for anoher |
| What Is Meant By A Chromosome Mutation? | A change in the number or sequence of genes in a chromosome |
| What Happens In A Deletion Chromosome Mutation? | Genes from the chromosomes are deleted |
| What Happens In Duplication Mutation? | Genes on the chromosomes are repeated |
| What Happens During Insertion Point Mutation? | One base is added |
| What Happens In A Substitution Mutation? | One base is replaced with another |
| What Happens In A Translation Mutation? | A section of one chromosome becomes attached to another |
| What Happens In An Inversion Mutation? | Genes on the chromosome are flipped (or rotate 180) |
| What Is Meant By A Frameshift Effect? | Each codon after mutation is altered leading to the wrong amino acid being used |
| Which Type Of Point Mutation Can Lead To An Expansion Of A Nucleotide Sequence? | Insertion |
| How Often Do Mutations Occur? | Randomly, rarely, spontaneously |
| Explain How A Mutation Can Lead To The Same Amino Being Produced? | Many amino acids have more that one codon |
| What Happens In A Translocation Mutation? | A section of one chromosome becomes attached to another |
| What Is A Mutation? | A random change to an organisms genome |
| Which Mutations Lead To Frameshift Effect? | Insertion and deletion |
| Name The Three Types Of Gene Mutation | •Substitution •Insertion •Deletion |
| Give An Example Of A Mutagenic Agent | •Mustard gas •U.V Radiation •X-rays |
| What Is The Result Of A Splice Site Mutation? | An intron could remain in the mature mRNA or an exon may have been removed |
| Name The Four Types Of Chromosome Mutations | • Translocation •Inversion •Deletion •Duplication |
| What Is A Mutagenic Agent? | Something which increases the frequency of mutations |
