Textbook Question
Chapter 22, Problem 22ESP
Private companies are offering personal DNA sequencing along with interpretation. What services do they offer? Do you think that these services should be regulated, and if so, in what way? Investigate one such company, 23andMe, at http://www.23andMe.com, before answering these questions.

Can you please check my answer and see if it is correct.
Question: In addition to master mix, what else must be added to each PCR tube? Why?
Answer:
In addition to master mix, the primers must be added to the PCR tubes. Each tube is also reserved for one individual’s specific section of DNA. So not only do primers needed to be added that are made specifically for the person’s DNA, but the DNA itself from the suspect needs to be added to the PCR tubes (DNA template strand). We also must have a control which contains sterile water, and one PCR tube reserved for DNA from the crime scene.
Brenda is a junior student in the biomedical program at her school. She is starting the PCR genetic testing lab activity. She is about to obtain her DNA sample but doesn’t want like the taste of NaCl solution. Her friend, Mark, let her use some of his DNA. What laboratory tule did the students break?
A. Obtaining and handling DNA sample without wearing googles or gloves
B. Improper use of human DNA samples
C. Violating Patient Confidentiality
D. Disposing of bio hazardous material in a regular trash

- Can you please check my answer and make sure it is correct. Question: Describe the two roles primers play in PCR. Answer: Primers are short sequences of single stranded DNA that mark both the ends of the target sequence to be amplified during PCR. One primer attaches to the top strand at one end (forward primer) and the other one attaches to the bottom strand at the other end of the segment (reverse primer). They are made specifically to attach to these sections of DNA because the nucleotides of the primers are complementary to the target sequence. Other than marking the starting and end points for PCR, primers are also necessary for the process because without them, DNA polymerase wouldn’t be able to synthesize the complementary strand of DNA because it can only add nucleotides to an existing piece.arrow_forwardState the five basic steps of DNA fingerprinting using the RFLP method.
