• chromosomal inversion

• chromosomal translocation

What type of chromosomal mutation occurred?

What are considered "negative" mutations?

• mutations in the DNA sequence that changes the resulting protein and harms the organism

• mutations in the DNA sequence that changes the resulting protein and benefits the organism

• mutations in the DNA sequence that produces the same protein

• all mutations are considered bad and harm the organisms

What are considered "positive" mutations?

• mutations in the DNA sequence that changes the resulting protein and harms the organism

• mutations in the DNA sequence that changes the resulting protein and benefits the organism

• mutations in the DNA sequence that produces the same protein

• all mutations are considered bad and harm the organisms

What are considered neutral mutations?

• mutations in the DNA sequence that changes the resulting protein and harms the organism

• mutations in the DNA sequence that changes the resulting protein and benefits the organism

• mutations in the DNA sequence that produces the same protein

• all mutations are considered bad and harm the organisms

Match the following

• a change in the DNA sequence

• Mutation

• a type of mutation where large sections of the chromosome are affected

• Frameshift mutation

• a type of mutation that doesn't result in a change in the amino acid sequence (same protein)

• Point mutation

• a type of mutation where one to few bases are substituted with different bases

• Chromosomal mutation

• a type of mutation caused by adding or deleting bases, affecting all the codons after the change

• Silent mutation

A frameshift mutation can occur with either _________ or __________ mutations.

• Addition, division
• Deletion, substitution
• Addition, substitution
• Addition, deletion
