Consider a benchtop synthesis reaction for a segment of DNA consisting of a helical arrangement of 14 nucleotides. (7 in each strand). The balanced chemical reaction for this hypothetical synthesis is given below.

If you allow 546.2 g of thymine, 456.7 g of adenine, 420.2 g of guanine and 514.6 g of cytosine to react in excess d-ribose and excess H3PO4, what mass of DNA may theoretically be produced?

Question 2 : The human body is said to contain approximately 50.0 grams of DNA in the entire body. If the number of nucleotides in ONE STRAND of DNA is approximately 3.0 x 106, and the average molar mass of a nucleotide is 327 g/mol, what is the average molar mass of an entire DNA double helix?

Question 3 : The total mass of DNA in the body is 50.0 g. If the number of nucleotides in ONE STRAND of DNA is approximately 3.0 x 106, and the average length of a single nucleotide is 0.34 nm, what is the length (in km) of one strand of DNA when it is stretched out to its maximum length (not in a helix)?

Question 4 : Using the average molar mass of a DNA double helix that you calculated in Question 2, what is the molarity of DNA in the human blood system. For the volume of blood, use the average volume of all the blood in a human body which is 4700 mL.

Your state Government hires interns for many of its offices. The Director of Human Resources has noticed that few of the interns submit all the needed paperwork and suspect that the problem is the form memo that goes out to interns. You've bee asked to revise the memo to make it more effective.

Pay is based on how many quarter or semester hours you have completed. At the end of each term, notify Human Resources, You may be eligible for a pay increase.

Design an experiment to knock out a certain gene of interest in the human genome. Outline the experiment, explaining the methods you would use, and also indicate how you would verify your experiment was successful at each step.

Why are gram-negative microbes and their related property of endotoxin of great concern to human health? Use the organism Neisseria meningitidis, and the resultant septicemia known as meningococcemia, to BRIEFLY apply the important concepts related to this question. Is there prevention for this outcome?
