Question 12: Why is the first step of this procedure (the mixing of haploids) performed on richplates?Because they are auxotrophs, they need the appropriate nutrients to grow and then to mate. The cells can'tmate efficiently if they are not able to undergo normal metabolism.To ensure the cells have enough nutrition to grow on the other minimal plates.We could have used any type of plate. We happened to choose the rich plates for this experiment.To ensure no mutations occur.We perform this procedure on rich plates in order to create a control for the experiments. If we mixed thehaploids on UMM plates, we would not have a prototrophic control strain for the experiment. Using the data provided below and the information from the Activity 3's Experiment section, answerthe following questions: Questions 12-15.Light tan represents the spots where the inoculum was plated, but showed no growth.Dark Tan represents the spots where inoculum was plated, but did show growth.UMM

Concept explainers

Genetic Recombination

Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.

Microbial Genetics

Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

For the juice samples in exercise 3-4, you will be using the pour plate technique. In this exercise, you will add juice to a petri dish and pour agar over the sample and mix. Why is the media (potato dextrose agar, PDA) kept in a water bath until you are ready to use it, and why must you work fairly quickly? (One response answers both questions). The media is already solid and will form chunks The media has a dye added to it that must be kept at 45°C until ready to use O PDA is a media that allows growth of many types of fungi, and the heat from the water bath keeps the fungal spores from growing. The media is kept liquid in the water bath with heat, removing the tube from the heat source will cause the PDA to solidify

Question 3 options: A Liquid gelatin positive for gelatinase B Clear area around bacterial growth on a starch plate after iodine is added means amylase is present C Clear zone around bacterial growth on a milk plate means caseinase is present D Solid gelatin after is positive for gelatinase E No clear zone around bacterial growth on milk plate means absence of casienase
After incubating for 24-48 hours, you retrieve your 4 agar plates for the osmotic pressure exercise from the 37°C incubator. You observe the following results: • Sa = Staphylococcus aureus • Pv = Proteus vulgaris Sa For each organism, you should indicate in the text box below: 1. At what salt concentrations (osmotic pressures) you saw growth. 2. The classification term you would use in order to classify the organism based on osmotic pressure. Choose your term based upon where you observed growth; not optimal growth. Each organism has only one classification term associated in describing its growth pattern(s). You will need to use the osmotic pressure classification descriptions and terms outlined in your lab manual.
