A company that manufactures cleansing products has synthesized two new organic compounds, chemicals A and B, which improve the cleaning power of dishwashing detergents. To determine the mutagenic capacity of the chemicals, the company tested the effect of the chemicals on Salmonella cells requiring histidine to grow (His cells). The table below shows the results of the test. A. Name the test used by the company. B. What does the test detect or estimate? C. Which chemical(s) would you identify as containing a mutagen? Why? D. What is the purpose of test 1? Why are colonies detected in test 1? E. Which chemical(s) would you identify as possible antimutagen? Why? No more than 75 words combined (parts a-d) Test Chemical added Average number of colonies observed after plating 10 cells on histidine and nutrients Growth media only 25+/-15 Growth media + Chemical A 1240+/-250 Growth media + Chemical B 5+/-5

What type of mutation occurred in mutant 3? a. Insertion b. Deletion c. Substitution 6. What type of mutation occurred in mutant 2? a. Insertion b. Deletion c. Substitution 7. According to Nature.com, "A genetic mutation known as CCR5-delta 32 is responsible for the two types of HIV resistance that exist. CCR5-delta 32 hampers HIV's ability to infiltrate immune cells. The mutation causes the CCR5 co-receptor on the outside of cells to develop smaller than usual and no longer sit outside of the cell." Which statement explains how these mutations occur? a. A mutation occurs when HIV enters the cell b. A mutation occurs when nucleic acids are replicated c. A mutation occurs during mitosis 8. A female, heterozygous for dark hair and freckles, married a male homozygous dominant for dark hair and he has no freckles. What % of their offspring will have dark hair and freckles? a. 56% b. 50% c. 19% d. 100% 9. A farmer wants to use the young plants that came from his P1 & P2 cross. He did gel electrophoresis on his plants to determine which ones were related to his P1 and P2. Which plants should he not choose? Answer: Choose all that apply. Y1 Y2 Y3 Y4 Y5 Y6 10. The central dogma states: the genes on DNA get transcribed into RNA, which get translated into a protein. a. Translated: RNA: transcribed: protein b. Transcribed: RNA: translated: protein c. Translated: DNA: transcribed: RNA d. Transcribed: DNA: translated: RNA 11. If the allele for tall pea plants (T) is dominant over the allele for short pea plants (t), what is the genotype of a homozygous tall pea plant? TTTT 12. Using the information from the question above, what percent of the offspring would be short if one parent is homozygous dominant and the other is heterozygous? 0% 13.
