The specificity of Watson-Crick nucleobase pairing enables the biological information to be encoded and passed down through generations of cells and organisms. This specificity arises from the chemical structure of the base pairs, namely the pattern of hydrogen bond donors and acceptors that stabilize only two pairing interactions] relative to the others. How many possible pairwise interactions could potentially exist at a single position within a sequence, including the correct pairs, and all possible other combinations of DNA bases?

proteins can interact with DNA through relatively weak forces, such as hydrogen bonds and can der Waals interaction, as well as through stronger electrostatic interactions such as ion pairs. Which types of interaction predominate for sequence specifics DNA binding proteins and for sequence independent binding proteins?
Draw the structure of the following DNA sequence (5’-AG-3’) hydrogen bonded through Watson-Crick base pairing to the complementary PNA sequence (Cterminus-TC-Nterminus). Make sure to include both the sugar phosphate backbone of your DNA sequence, as well as the peptide backbone of your PNA sequence. DNA: 5’-AG-3’ PNA: (C)-TC-(N)
Which positions in the purine ring of a purine nucleotide in DNAhave the potential to form hydrogen bonds but are not involved in Watson-Crick base pairing?
A duplex DNA molecule contains a random sequence of the four nucleotides with equal proportions of each. What is the average spacing between consecutive occurrences of the sequence 5'-ATGC-3'? Between consecutive occurrences of the sequence 5'-TACGGC-3'?
Which of the following (A through E ) would you expect to find in a nucleotide chain constructed for Sanger sequencing?
In reversible terminator sequencing, how would the sequencing process be affected if the 3′-end-blocking group of each nucleotide were replaced with the 3′-H present in the dideoxynucleotides used in Sanger sequencing?
Compare the structural features that distinguish B-DNA from A-DNA and Z-DNA. What is known about the functional properties of these variants of B-DNA, the Watson–Crick structure?
In addition to the standard base-paired helical structures, DNA can form X-shaped hairpin structures called cruciforms in which most bases are involved in Watson–Crick pairs. Such structures tend to occur at sequences with inverted repeats. Draw the cruciform structure formed by the DNA sequence TCAAGTCCACGGTGGACTTGC.
Why is the double-helical structure of DNA stabilized at moderate to high ionic strength?
What two basepair changes can occur when G tautomerizes to the enol form? Recall that the tautomerization can occur when G is a free dNTP prior to DNA replication or when G is incorporated into dsDNA just before DNA replication. Draw both of these bp changes out. Are they transitions or transversions?
5-bromouracil is a base analog. It looks chemically similar to a thymine, and able to pair with adenine. But it often shifts to its enol form, and in its enol form, it can pair with Guanine instead of Adenine. What kind of mutation would most likely result from incorporation of 5-bromouracil into a DNA strand: insertion, deletion, frameshift, or substitution?
