Textbook Question
Chapter 9, Problem 26PDQ
A genetics student was asked to draw the chemical structure of an adenine- and thymine-containing dinucleotide derived from DNA. His answer is shown below. The student made more than six major errors. One of them is circled, numbered 1, and explained. Find five others. Circle them, number them 2–6, and briefly explain each by following the example given.

The non-Watson-Crick base pair shown in A is much less stable than the base
pairs shown in B and C, because the smaller size of the two pyrimidine bases
induces a distortion in the structure of the double helix that decreases the
stability of the helix when compared to helices with the normal Watson-Crick
base pairs.
The base pair shown in B is found in BOTH DNA and RNA
The base pair shown in C is found ONLY in RNA and NOT DNA
The base pair seen in B is more stable than the Watson-Crick base pair shown in
C partly because of a larger number of hydrogen bonds and partly because of
more favourable pi-stacking interactions with adjacent base pairs.
DNA sequences have an alphabet {A,C,G,T}.
How many DNA sequences of length n are there? (Two DNA sequences are the same if one is
the reverse of the other).
A compact disc (CD) stores about 4.8 × 109 bits of information in a 96 cm2 area. This information is stored as a binary code—that is, every bit is either a 0 or a 1.
how many bits would it take to specify each nucleotide pair in a DNA sequence?
how many CDs would it take to store the information contained in the human genome?
