Study Notes
Lesson 4: Mutation
- Lesson objective: Identify mutations and classify different types of mutations.
- Mutation: A change in the sequence of nucleotide bases that make up a gene or a strand of DNA.
- Gene: A unit of hereditary information that occupies a fixed position on a chromosome.
Warm-Up
- Describe organisms in the pictures provided.
Assess Prior Knowledge
- Identify the mutation shown in the image. How does this mutation affect red blood cells? (Illustrative image of sickle cell anemia)
Table 3: Mutations
- Mutation Type | Analogy Sentence
- --|---|
- Normal | THE BIG FAT CAT ATE THE WET RAT
- Missense (substitution) (wrong amino acid) | THE BIZ FAT CAT ATE THE WET RAT
- Nonsense (substitution) (premature stop codon) | THE BIG RAT
- Deletion (causing frameshift) | THB IGF ATC ATA TET HEW ETR AT
- Insertion (causing frameshift) | THE BIG ZFA TCA TAT ETH EWE TRA
- Duplication | THE BIG FAT FAT CAT ATE THE WET RAT
- Expanding mutation (tandem repeats) | THE BIG FAT CAT ATE THE WET RAT Generation 1 THE BIG FAT CAT CAT CAT Generation 3 THE BIG FAT CAT CAT CAT
