Chemistry

Consider a benchtop synthesis reaction for a segment of DNAconsisting of a helical arrangement of 14 nucleotides. (7 in eachstrand). The balanced chemical reaction for this hypotheticalsynthesis is given below.

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

Question 2 : The human body is said to contain approximately50.0 grams of DNA in the entire body. If the number of nucleotidesin ONE STRAND of DNA is approximately 3.0 x 106, and the averagemolar mass of a nucleotide is 327 g/mol, what is the average molarmass of an entire DNA double helix?

Question 3 : The total mass of DNA in the body is 50.0 g. If thenumber of nucleotides in ONE STRAND of DNA is approximately 3.0 x106, and the average length of a single nucleotide is 0.34 nm, whatis the length (in km) of one strand of DNA when it is stretched outto its maximum length (not in a helix)?

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