DNA fragments that are 500 bp, 1000 bp, and 2000 bp in length are separated by gel electrophoresis. Which fragment will migrate farthest in the gel?
a. The 2000-bp fragment
b. The 1000-bp fragment

PCR is a molecular biology technique where template DNA is amplified using a primer and oligonucleotides. The reaction is catalyzed by a thermostable DNA polymerase and in a particular reaction, the template strands are denatured at 95˚C. For strand hybridization, the melting temperature is 55˚C. What do you predict about the average duration of H bonds at the high temperature in comparison to the low temperature?
Which of the following best describes the process of DNA seqencing.
a. DNA is seperated on a gel and the different bands are labled with flouroscent nucleotides and scanned with a laser.
b. A laser is used to flurorescently label the nucleotides present with in the DNA , the DNA is run on a gel and then the DNA is droken into fragments
c. Nucleotides are scanned with a laser and incrprorated into the DNA that has been seperated on a gel and then DNA is amplified with PCR.
d. fragments of DNA are produced in a reaction that lables them with any of four different fluroscent dyes and the fragmented then are run on a gel and scanned with laser
e. DNA is broken down into its constituents nucleotides and the nucleotides are then run on a gel and purified with a laser
