Mutations Vocab Practice

Chromosomal mutations Match the term with the correct description. Chromosomal Mutation A change in the structure of a chromosome or the entire chromosome Translocation Chromosome pieces are moved onto another chromosome Inversion Chromosome segment is inserted in reverse order Duplication A segment of a chromosome is repeated Deletion A segment of a chromosome is removed Point Mutations Match each term to the correct description Insertion One or more nucleotides are added to a gene Frameshift mutation The addition or deletion of one or more nucleotides that changes the number of complete codons Point mutation A change in one nucleotide Deletion One or more nucleotides are removed from the gene Substitution One nucleotide is switched for another If the original DNA is ATAACGCCTATT, how many codons are there? 3 4 5 12 For the scenario above, when the "G" is deleted, how many complete codons would there then be? (Original - ATAACGCCTATT, "G" removed, New- ATAACCCTATT) 3 4 5 12 Using the following DNA sequence, determine the type of mutation that has occurred with the new sequence. Original: TAC ACC TTG GCG ACG ACT New sequence Type of mutation TAC ATC TTG GCG ACG ACT Substitution TAC GAC CTT GGC GAC GAC T Insertion TAC ACC TTG GGA CGA CT Deletion A geneticist found that a particular mutation had no effect on the protein coded by a gene. What do you think is the most likely type of mutation in this gene? Deletion Insertion Substitution Translocation Deletion Translocation Inversion Duplication
