Which of the following components of PCR ensures amplification of the target DNA sequence only, despite the presence of many other DNA sequences?

Briefly describe how a negative sense ssDNA virus such as Parvovirus accomplishes replication of its genetic material.

You plate 100 mL of a sample whose dilution is 10-5 that produced 142 colonies. Determine the original cell density of the broth culture.

If an organism grows on mannitol salt agar you can conclude that the microbe is a halophile and that it is a Gram-positive bacterium.  

You plate 100 mL of a sample whose dilution is 10-5 that produced 142 colonies. Determine the original cell density of the broth culture.

In the blood agar test, the procedure indicated making a throat culture and taping the plates’ edge. Why is tapping the plates’ edge important if all the students are healthy when they take the throat samples?

Determine the type of medium that MSA is and the role of D-Mannitol.  

Consider the image below of the disk diffusion test results of an unknown microbe to answer the questions.   1. Based on what you can observe, select the alternative with the largest zone of inhibition. [option1] 2. Based on what you can observe, select the alternative with the smallest zone of inhibition. [option2] 3. Considering this is an unknown sample, consider if the statement below is true or false.  To report if the microbe is susceptible, intermediate, or resistant, you need the table that shows the zone of inhibition diameters. Once you have the table, you can use the results to guide the appropriate prescribing treatment. [option3]
