Want to know:
A researcher interested in the control of the cell cycle identifies a yeast mutant (cd-) whose rate of cell division is temperature sensitive. At low, permissive temperatures, the mutant strain grows normally and produces yeast colonies having a normal size. However, at elevated, restrictive temperatures, the mutant strain is unable to divide and produces no colonies. She has a yeast genomic library made in a plasmid vector (containing the ura3+ selectable marker) and a ura3- cd- mutant, and she wants to clone the gene affected in the cell division mutant.What steps should she take to accomplish this objective?

- Describe how individuals with one (heterozygous) or two (homozygous) copies of the wild-type GA3H allele can have the same phenotype.
- 9.26 Mycobacterium leprae is an intracellular bacterium that is the causative agent of leprosy, a chronic disease that infects the skin, nerves, and mucous membranes. It has not been possible to grow the bacterium in a culture medium, unlike its relative Mycobacterium tuberculosis, the causativeagent of tuberculosis (TB). M. tuberculosis can also grow intracellularly, as in the lungs it is taken up by alveolar macrophages and can multiply unchecked. The following table compares the genomes of these two organisms. M. leprae-M. tuberculosis:*Genome size (Mb): 3.27 -4.41*Percent of genome encodingproteins: 49.5 -90.8*Protein-coding genes (ORFs): - - 1,604- 3,959*Pseudogenes: 1,116- 6*Gene density (bp per gene): - - 2,037- 1,114*Average gene length: - 1,011-1,012a. Pseudogenes are nucleotide sequences that no longer produce functional gene products because they have accumulated inactivating mutations. Why might M. leprae have many more pseudogenes than M. tuberculosis?b. What analyses would you perform to understand how these two bacteria differ in terms of the enzymatic functions they can carry out?c. How might your analyses help you understand how to culture M. leprae?
