Use the following data to answer the questions 1 and 2. In a sample of double-stranded DNA from a particular bacterium with a circular chromosome, 43% of the nucleotide bases are Guanine (G). Sodium hydroxide (NaOH) "denatures" DNA by disrupting the hydrogen bonds and causing the strands to separate. You can separate one strand from the other by gel electrophoresis; one strand runs faster in the gel than the other strand. You find that the "faster" strand has 62% G.
1. What percentage of nucleotide bases in the original double-stranded molecule are A?a. 7%b. 14%c. 43%d. 57%e. Cannot be determined from the information provided.
2. What percentage of nucleotide bases in the faster single-strand are C?a. 0%b. 7%c. 24%d. 38%e. Cannot be determined from the information provided.

There is approximately 2,000 cubic kilometers of water stored in rivers around the world. Using the terms water cycle, flux and pool, explain under what situations removing 1000 cubic kilometers per year from rivers for human use could be sustainable..
How many net ATP are gained through glycolysis? (the pathway itself, not substances that will eventually go through the electron transport chain)?
If NAD+ is an electron acceptor that becomes NADH and the NADH then donates a proton to ATPase, should not NADH now become NAD- since it lost it's proton but still has electron?
Imagine that you have been studying the population biology of ground squirrels on the UCSC campus for a number of years and have obtained the following information.
Describe how those mutations can potentially result in cancer. Make sure you list all references used for information and images.
A calorie is the amount of heat required to raise the temp of one gram of water by 1°C (1 cal = 4 J). A marine iguana from the Galapagos Islands weighs about two kg.
