Question

drag each tile to the correct location. identify the types of mutations represented by the change in each dna sequence. change in nucleotide sequence type of mutation atgc → atc atgc → attc attcgc → attcggc acgt → tgca attg → attgattg attc (chromosome 1) cgattc (chromosome 2) → atcga (chromosome 1) tcttc (chromosome 2)

Explanation:

1. ATGC → ATC: A single - base substitution where G is replaced by T, so it's a point mutation (specifically a substitution mutation).
2. ATGC → ATTC: Another single - base substitution with G replaced by T, a point mutation (substitution).
3. ATTCGC → ATTCGGC: An insertion mutation as an extra G is inserted.
4. ACGT → TGCA: A transversion mutation (a type of substitution where a purine is replaced by a pyrimidine and vice - versa).
5. ATTG → ATTGATTG: A duplication mutation where the sequence ATTG is repeated.
6. ATTC (chromosome 1) CGATTC (chromosome 2) → ATCGA (chromosome 1) TCTTC (chromosome 2): A translocation mutation as parts of different chromosomes are rearranged.

Answer:

ATGC → ATC: Point Mutation (Substitution)
ATGC → ATTC: Point Mutation (Substitution)
ATTCGC → ATTCGGC: Insertion Mutation
ACGT → TGCA: Transversion Mutation (Substitution)
ATTG → ATTGATTG: Duplication Mutation
ATTC (chromosome 1) CGATTC (chromosome 2) → ATCGA (chromosome 1) TCTTC (chromosome 2): Translocation Mutation
