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.
For what purposes is DNA extraction done? (give at least 3 purposes for which you may need to extract DNA)
What are the different types of PCR and their application? Please answer at your own words.

- 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_forwardBrenda is a junior student in the biomedical program at her school.
