- Arrange the following molecules from least to most specific with respect to the original nucleotide sequence: RNA, DNA, Amino Acid, Protein
- Identify two structural differences between DNA and RNA.
- Suppose you are performing an experiment in which you must use heat to denature a double helix and create two single stranded pieces. Based on what you know about nucleotide bonding, do you think the nucleotides will all denature at the same time? Use scientific reasoning to explain why.

1. The figure below shows a DNA double helix and its nucleotide
sequence.
A. A homodimeric helix–turn–helix protein binds to a DNA
fragment containing this sequence. Its preferred half-site is
AACAC. Show where the two recognition helices in the protein
contact the DNA.
B. Are protein–DNA contacts primarily in the major or the minor
groove of DNA? What parts of the nucleotides contact the amino acid
side chains of the protein to provide most sequence specificity?

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...

Each of the following statements about the structure of DNA may be either true or false. Choose the appropriate answer for each of these statements. Bonding between adenine and thymine on opposite strands involves two hydrogen bonds. Nitrogenous bases are located on the outside of the double helix: phosphates are located towards the middle of the double helix. Bonding between guanine and cytosine on opposite strands involves three hydrogen bonds. DNA and RNA are structurally different due to the difference...
