Mutation = Mutations- Change occur when DNA is damaged or changed so the code is no longer the same. Can occur in any cell. They can be beneficial, bad, or neutral
6
1. Substitution (Point mutation) – a change in a single nitrogen base pair. THE DOG BIT THE CAT THE DOG BIT THE CAR
7
1 point mutation in a hemoglobin codon creates this disease.

2. Frame shift-A single base is inserted or deleted from the DNA. THE FAT CAT SAT TAH EFA TCA TSA T TEF ATC ATS AT

3. Insertion-All or part of a codon is inserted in the DNA. THE FAT CAT SAT THE NOT FAT CAT SAT
12
4. Deletion-All or part of a codon is deleted from the DNA. THE FAT CAT SAT THE CAT SAT

c.) translocation is the result of chromosomal breakage but the broken segment transfers itself to a broken segment of another chromosome.translocation d.) deletion - Deletion occurs when a chromosome breaks and a portion of the chromosome is lost.deletion e.) inversion - a section of the chromosome is inverted (reversed) on the same chromosomeinversion

a.) trisomy - an extra chromosome is present. Duplication of a portion of a chromosome may attach to a chromosome or remain as a separate fragment.trisomy b.) monosomy - a chromosome is missingmonosomy
