Label each statement as pertaining to DNA, RNA, or both.
- The polynucleotide is double stranded.
- The polynucleotide may contain adenine.
- The polynucleotide may contain dGMP.
- The polynucleotide is a
polymer of ribonucleotides.

(a)
Interpretation:
Whether the statement "the polynucleotide is double stranded" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
There are two types of nucleotide. They are DNA and RNA. Nucleic acids are composed of monomers called nucleotides.
Answer to Problem 22.27P
DNA
Explanation of Solution
DNA consists of two polynucleotide strands which wind into a right-handed double helix.
RNA is single stranded structure.

(b)
Interpretation:
Whether the statement "the polynucleotide may contain adenine" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
There are two types of nucleotide. They are DNA and RNA. Nucleic acids are composed of monomers called nucleotides.
There are five common nitrogen-containing bases that are present in nucleic acids; cytosine, uracil, thymine, adenine and guanine.
Answer to Problem 22.27P
Both DNA and RNA
Explanation of Solution
There are five common nitrogen-containing bases that are present in nucleic acids; cytosine, uracil, thymine, adenine and guanineDNA contains the bases A, G, C, and T.
RNA contains the bases A, G, C, and U.

(c)
Interpretation:
Whether the statement "the polynucleotide may contain dGMP" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
dGMP stands for Deoxyguanosine 5'-monophosphate. Deoxyribonucleotides are derived from 2-deoxyribose.
Answer to Problem 22.27P
DNA
Explanation of Solution
dGMP stands for Deoxyguanosine 5'-monophosphate. Deoxyribonucleotides are derived from 2-deoxyribose.DNA is a polymer of deoxyribonucleotides.
Therefore, dGMP present in DNA.

(d)
Interpretation:
Whether the statement "the polynucleotide is a polymer of ribonucleotides" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
To make a Nucleotides; a phosphate group is added to the 5'-OH of a nucleoside.
Nucleotides are named by adding the term 5'-monophosphate to the name of the nucleoside from whichthey are derived.
Ribonucleotides are derived from ribose. Deoxyribonucleotides arederived from 2-deoxyribose.
Answer to Problem 22.27P
RNA
Explanation of Solution
Ribonucleotides are derived from ribose. Deoxyribonucleotides are derived from 2-deoxyribose. DNA is a polymer of deoxyribonucleotides.
RNA is a polymer of ribonucleotides.

Using Maxwell’s velocity distribution, one can also calculate the mean velocity and the most probable velocity (mp) of a collection of molecules. The equations used for these two quantities are vmean=(8RT/πM)1/2 and vmp=(2RT/M)1/2 These values have a fixed relationship to each other.(a) Arrange these three quantities in order of increasing magnitude.(b) Show that the relative magnitudes are independent of the molar mass of the gas.(c) Use the smallest velocity as a reference for establishing the order of magnitude and determine the relationship between the larger and smaller values.arrow_forwardThe reaction of solid dimethylhydrazine, (CH3)2N2H2, and liquefied dinitrogen tetroxide, N2O4, has been investigated for use as rocket fuel. The reaction produces the gases carbon dioxide (CO2), nitrogen (N2), and water vapor (H2O), which are ejected in the exhaust gases. In a controlled experiment, solid dimethylhydrazine was reacted with excess dinitrogen tetroxide, and the gases were collected in a closed balloon until a pressure of 2.50 atm and a temperature of 400.0 K were reached.(a) What are the partial pressures of CO2, N2, and H2O?(b) When the CO2 is removed by chemical reaction, what are the partial pressures of the remaining gases?arrow_forward
- One liter of chlorine gas at 1 atm and 298 K reacts completely with 1.00 L of nitrogen gas and 2.00 L of oxygen gas at the same temperature and pressure. A single gaseous product is formed, which fills a 2.00 L flask at 1.00 atm and 298 K. Use this information to determine the following characteristics of the product:(a) its empirical formula;(b) its molecular formula;(c) the most favorable Lewis formula based on formal charge arguments (the central atom is N);(d) the shape of the molecule.arrow_forwardHow does the square root mean square velocity of gas molecules vary with temperature?
