Molds and Yeasts

Both molds and yeasts are considered fungi. Using the South University Online Library or the Internet, read and research about molds and yeasts.

Based on your research, respond to the following:

1. Compare and contrast between molds versus yeasts. (Note: Use the Mold and Yeast Comparison Template to compare and contrast between molds versus yeasts.)

2. Human infectious diseases are caused by fungi classified as superficial, cutaneous, subcutaneous, and systemic mycoses. What specific characteristics distinguish each of these categories?

3. What are the regions of the human body where mycotic diseases can be observed?

PCR

PCR has been developed as a technology for correcting gene defects, thereby advancing the diagnostic aspects of molecular biology, especially for infectious and diagnostic diseases.

Using the South University Online Library or the Internet, research on PCR. Based on your research, respond to the following:

1. What is PCR? Describe the technique in detail.

2. What enzyme is used in this process and how is the enzyme used in PCR different from others?

3. What is that enzyme's function in the cell?

4. How has PCR changed microbiology?
