The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutationswere associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changeshave different genetic bases. How does this study support the concept that natural selection is not random

You perform an experiment in which chromatin is isolated from sea urchin sperm cells and briefly digested with micrococcal nuclease. When the chromatin proteins are removed and the resulting purified DNA is analyzed by gel electrophoresis, you observe a series of DNA fragments that are multiples of 260 base pairs in length (that is, 260 bp, 520 bp, 780 bp, and so forth). a) Although these results differ somewhat from the typical results discussed in the chapter, explain why they still point to the likely existence of nucleosomes in this cell type. b) What can you conclude about the amount of DNA that is associated with each nucleosome

Determine the rate of oxygen consumption at each temperature for comparison. Then divide the higher rate by the lower rate to obtain the difference (ratio) between the two temperatures. Round your answer to the nearest 0.1. It can be concluded that mouse respiratory rate (increases or decreases) when temperature is lowered. In this experiment there was a fold difference in respiratory rate at the two temperatures.

Assume that one backbone of a DNA molecule has the sequence given below. A-T-G-G-G-G-G-C-G-A-T-A-T-T-T-T-A-T-C-C-G-A-C-G For this sequence: give the expected sequence of the other DNA backbone. T-A-C-C-C-C-C-G-C-T-A-T-A-A-A-A-T-A-G-G-C-T-G-C give the RNA sequence transcribed from the original DNA backbone. U-A-C-C-C-C-C-G-C-U-A-T-A-A-A-A-U-A-G-G-C-U-G-C give the Amino Acid sequence of the protein built from the original DNA backbone.
