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 substitution atgc → attc attcgc → attcggc acgt → tgca attg → attgattg attc (chromosome 1) cgattc (chromosome 2) → atcga (chromosome 1) tcttc (chromosome 2)

Explanation:

1. For ATGC → ATC, one nucleotide (G) is replaced by another (T), so it's substitution.
2. For ATGC → ATTC, one nucleotide (G) is replaced by another (T), so it's substitution.
3. For ATTCGC → ATTCGGC, an extra G is added, so it's insertion.
4. For ACGT → TGCA, the sequence is reversed, so it's inversion.
5. For ATTG → ATTGATTG, the ATTG sequence is repeated, so it's duplication.
6. For the chromosome - based change, parts of different chromosomes are rearranged, so it's translocation.

Answer:

ATGC → ATC: substitution
ATGC → ATTC: substitution
ATTCGC → ATTCGGC: insertion
ACGT → TGCA: inversion
ATTG → ATTGATTG: duplication
ATTC (chromosome 1) CGATTC (chromosome 2) → ATCGA (chromosome 1) TCTTC (chromosome 2): translocation
