FACT or BLUFF. Write FACT if the statement is correct and BLUFF if it is incorrect. __________1. Changes in the DNA sequence may delete such protein or change its structure. __________2. Changes in the protein structure or level of expression may lead to changes in cellular properties and behavior but the organism is unaffected. __________3. Mutation may be induced by factors called mutagens. Mutagens are commonly in the form of toxic chemicals, and harmful radiation. __________4. Mistakes occur in DNA replication, mitosis, and meiosis and can alter the DNA sequence and length. __________5. Mutations can only occur in sperm cell and egg cell. __________6. Mutations affect the reproductive cells of an organism by changing the sequence of nucleotides within a gene in a sperm or an egg cell. __________7. Gene mutation is a temporary change in the DNA sequence that makes up a gene. __________8. Chromosomal mutation occurs at the chromosome level resulting in gene deletion, duplication or rearrangement that may occur during the cell cycle and meiosis. __________9. A severe mutation may lead to cell death and may have no effect on the body. __________10. Mutations are all of the time useful for the species. For example, a mutation in blood proteins prevents viruses or parasites to thrive in host organisms. i
