1. Identify the problem with this statement: PCR-based systems often yield results for a tiny sample of relatively poor-quality DNA?
2. Name one type of cell in the human body from which you could NOT extract chromosomal DNA and explain why.
3. The final result in RFLP analysis looks like a simplified supermarket bar code. The latter is absolutely unique. Is the RFLP pattern unique?
4. The final result in the PM + DQA1 test is seen as blue dots on a white strip. Why are the positive and negative controls so important in this test?
1. PCR is polymerase chain reaction. It is used to amplify a DNA sample.
PCR produces good quality DNA.
So, the correction will be good quality DNA.
PCR-based systems often yield results for a tiny sample of relatively good-quality DNA
2. The cell from which chromosomal DNA cannot be extracted is RBC. As, RBC lacks nucleus. When RBCs mature they lose their nucleus.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
