4. The figure below is a cartoon
representation of a large biomolecule called a
peptide, made up of different types of amino
acids. Near the bottom of the figure are two
chemical groups that are part of different
amino acids in different positions along the
chain. Based on the structures of those
groups, what type of force is represented by
the dashed red line? Be sure to consider any
charges that are shown.

Give the general structure of amino acid.
Doxorubicin, shown here, is an important chemotherapy drug used to treat avariety of cancers, including bladder cancer, breast cancer, and certain forms of leukemia. Doxorubicin works by binding to DNA in such a way that a portion of it penetrates the DNA double helix— a process called intercalation. During transcription— the process that forms RNA— portions of the DNA strands are temporarily separated for the base sequence to be read and then are reconnected. With bound doxorubicin, however, the double helix does not reform properly after the strands are separated, which disrupts replication— the process that forms an identical copy of DNA. Which portion of doxorubicin do you think intercalates into the DNA double helix, and why do you think it has little difficulty doing so?

The C-N bond formed in this process is called a peptide bond. Peptide bonds have a few properties that might be unexpected. a) One property is that the molecular geometries around the C and N atom in the peptide bond are generally planar with bond angles of approximately 120 degrees. Provide an explanation for why the peptide bond would have this property, using Lewis structures, VSEPR theory and/or valence bond theory as appropriate.arrow_forwardWhich of the following statements islare true about fat soluble vitamins (A.
