6. The starting scquence of a gene changed from AUGTTCGACGTG, to AUGTTTTCGACGTG What type of mutation is this? To answer the question, please explain: I) what the mutation is? 2) what types of mutation do you know? 3) what are the possible outcomes of mutations?

5.) You have identified a mutant with the following phenotype:  a) Explain what has most likely happened to the chromatin in the mutant fly.  b) Which enzyme do you think has undergone a mutation in your mutant fly? There is more than one correct answer, just give one possibility.  c) How did the mutation in the enzyme you identified in part b affect the activity of that enzyme in order to see the phenotype we observed above?

8. A mutant that has a nutritional requirement for growth is an example of a(n) A) heterotroph B) auxotroph C) autotroph D) organotroph 9. In the Ames test the number of histidine auxotroph colonies growing on media lacking histidine when exposed to a potential chemical mutagen is. proportional to the likelihood that the chemical is mutagenic. A) Directly B) Inversely 10. Thymine dimers result from A) ionizing radiation B) nucleoside analogs C) non-ionizing radiation D) none of the above 12. RecA proteins are NOT required for homologous recombination? A) True B) False 13. Increasing genetic variability by the uptake of DNA from the environment is A) transduction B) transformation C) a mutation D) conjugation 14. Which of the following features are common to transformation, transduction, and conjugation? (1) unidirectional transfer of genes (2) incomplete gene transfer (3) homologous recombination (4) meiosis occurring in the recipient A) 1, 2, 4 B) 1, 2, 3 C) 3,4 D) 1,2 15. What is…

Can you explain how to find what mutation 2 is with elaborate step?
