To find genes whose protein products are important for threonine synthesis, you perform a mutagenesis to find mutants that require a source of threonine to grow. mtl mt2 mt3 nt4 mt5 mt6 mt7 mt8 mt9 wt You find a total of nine mutants, all of which have recessive phenotypes. You perform complementation tests with all of your mutants. Below are the results for your complementation tests. A (+) means growth and a (- means no growth: mtl mt2 mt3 mt4 mt5 mt6 mt7 mt8 mt9 Wt a. How many complementation groups did you identify? For each complementation group, indicate which mutants belong to that complementation group. ++ I++++ + + + + 主+4. Normal yeast cells can survive on a diet of sugars, a few simple salts and one vitamin. They can make all of their amino acids and other vitamins using what can be found in their diet. You identify a mutant strain that can only survive if given alanine, which is one of the amino acids. The mutation is recessive. Based on this information, what would you predict that the normal function of the dominant allele is?
- The photos above show flowers from Arabidopsis plants. One plant is wild-type (unmutated); the other carries a mutation in one of its ABC floral identity genes. This mutation causes sepals and petals to form instead of stamens and carpels. Refer to Figure 10.8 to decide which gene (A, B, or C) has been inactivated by the mutation.Which description is an example of a phenotype? A certain duck has a blue beak A mutation occurred to a flower Most cheetahs live solitary lives both a and c4. Allele specific oligo-nucleotide hybridization is a genetic test used to look for single nucleotide polymorphisms (SNPS) associated with genetic diseases. It uses short sequences of labeled DNA as probes to bind onto either the normal allele or mutated allele in a patient's sample. Given that hemocystinuria is an autosomal recessive disease, use the results from the ASOH test below to determine the GENOTYPE and PHENOTYPE of the newborns born at Henry Mayo Hospital this week.

- Describe 6 different types of mutations that can occur at the chromosomal and nucleotide levels. Make sure to include 3 types of each.6. A diploid strain of yeast was made by mating a haploidstrain with a genotype w−, x−, y−, and z− with a haploidstrain of opposite mating type that is wild type for thesefour genes. The diploid strain was phenotypically wildtype. Four different X-ray-induced diploid mutantswith the following phenotypes were produced fromthis diploid yeast strain. Assume a single new mutation is present in each strain.Strain 1 w− x+ y− z+Strain 2 w+ x− y− z−Strain 3 w− x+ y− z−Strain 4 w− x+ y+ z+When these mutant diploid strains of yeast go throughmeiosis, each ascus is found to contain only two viablehaploid spores.a. What kind of mutations were induced by X-rays tomake the listed diploid strains?b. Why did two spores in each ascus die?1. ls a random mutation more likely to be beneficial or harmful? Explain your answer 2. Distinguish between spontaneous and induced mutations. Which are more harmful? Which are avoidable?

You are studying the biochemical pathway of purrine production. (Purrines are a type of nucleotide used in feline DNA, a little different than the purines in the DNA of lower species like humans.) You have several mutants that cannot make purrine, and you do complementation tests to see how many different genes you've identified. Here are your data: mutant 1 4 6 8 1 3 4 5 + 6 + + + 8. + + 9 + a) What is the deal with mutant #1 and why must you ignore it when figuring out complementation groups? b) For the rest of the problem, ignore mutant #1. List your complementation groups. Hint: every single one of your mutants (except #1 of course) must be in a group. c) How many genes did you, therefore, identify?3b.
