Explain what mutations are and why they can be such a problem. In addition to that, please explain the similarities and differences between frameshift and point mutations. do not simply copy from your book, my notes, or a website.

1. Would a single chicken egg from the grocery store be a good source of DNA for the extraction performed in lab? Why or why not?

2. How would your results of the extraction performed in lab compare if you extracted DNA from a strawberry (octoploid) versus a human (diploid)?

3. A human hair is approximately 1 ìm thick, while the diameter of the DNA double helix is about 2 nm. Calculate how many strands of DNA double helix would have to bundle together to produce a thread that was the same thickness as five hairs.

If you were to take all of the DNA chains from all of the chromosomes in your body and stitch them all together into one gigantic linear double helix, how long would that helix be? Use the fact that a 1 kilobase pair (kbp) double helix of DNA is 340 nanometers in length (340 nm) and that the haploid human genome contains 3.3 x 109 bp of DNA to make your calculation (and remember that human cells are diploid!). Assume that the human body contains 1013 cells and use the conversion factor 1 Meter = 6.2 x 10-4 Miles. Show your work (with all appropriate unit conversions) and express your answer in solar units (1 solar unit = distance from earth to the sun = 9.1 x 107 miles).
