What does each diffrent band on a DNA profile represent?
What does each diffrent band on a DNA profile represent?
Homework Answers
The different band on a DNA profile represent pieces of DNA in different sizes. There is series of the band with each band containing DNA molecule of a particular size. The band furthest from the start of the gel contain the smallest fragmenr of DNA.

14. Like a ladder. Circular DNA from the SV40 virus was isolated and subjected to gel electrophoresis. The results are shown in lane A (the control) of the adjoining gel patterns. (a) Why does the DNA separate in agarose gel electrophoresis? How does the DNA in each band differ? (b) What types of DNA do the various bands represent? (c) What is the significance of the fact that more of the DNA is in slower-moving forms?

You isolate plasmid DNA from bacteria (Questions 7-10) 7) A plasmid is an extrachromosomal circular DNA frequently found in prokaryotes. Aside from being smaller, how is it different from the prokaryotic genome? You place equal amounts of plasmid DNA in 4 different tubes and incubate the DNA with increasing amounts of the enzyme topoisomerase I for 1 hour (0 enzyme units 0.25 enzyme units, 0.5 enzyme units and 1 enzyme unit). You then analyze the plasmid...
