Match each step in a PCR cycle to its description. Unwind DNA to expose single strands A. Extension Temperature drop that allows primers to hybridize with the template B. Heat based denaturation Temperature increase that enables Taq to become maximally active C. Annealing

You PCR amplify a 500 bp (base pairs) piece of DNA that has
diagnostic value in determining whether a patient has a mutation
within a specific DNA region. You know that this DNA segment of the
“normal” gene does not include an EcoRI restriction site; but the
mutated DNA segment of the same gene contains an EcoRI restriction
site due to a point mutation at the 100th bp from the 5’ DNA end.
After PCR amplification, you subject your DNA...

Discuss how the technique of PCR allows a scientist to quickly clone a particular piece of DNA. Be clear about the importance of 2 primers and Taq DNA polymerase. Make sure you explain how you do a PCR – what is needed.

What is the difference between regular PCR and RT-PCR? In RT-PCR you can measure the amount of DNA copied by adding a fluorescent dye. The fluorescence increases as the desired sequence is amplified. O In PCR, there is a higher chance of contamination with undesired samples because primers are less specific than in RT-PCR In RT-PCR, new sequences can be added each cycle which makes the process more dynamic and efficient. In PCR, the temperatures vary more than in RT-PCR...

1. Explain why, when PCR is used to amplify the same region of DNA from two different people, the size of the DNA fragment(s) generated may be different? 2. What characteristic of the DNA molecule makes it possible to use electrophoresis to separate DNA molecules by size? Explain why this characteristic is important for electrophoresis and what part of the DNA molecule creates this characteristic. 3. You are performing PCR. After four cycles of PCR, how many double-stranded copies of...

What is the average radius of a piece of double-stranded DNA in water that has a link length of 5.9 nm and and is 3019228 links long If the two strands of the double-stranded DNA are separated, each chain now has a radius of 530 nm. What is the link length for single-stranded DNA?

EXPLAIN each answer thoroughly. There are two common goals when using PCR to amplify DNA. A. Make lots of copies of a specific DNA sequence to use in cloning (preparative PCR) B. Detect the presence or relative amount of a specific gene under varying conditions (analytical PCR) *Remember: PCR is very similiar to DNA replication, but uses a DNA polymerase to amplify only specific parts of DNA sequence based on the sequence of the primers. 3. For which goal (A...
