Textbook Question
Chapter 18, Problem 18.13PS
Nucleoli. Indicate whether each of the following statements is true (T) or false (F). If false, reword the statement to make it true.
(a) Nucleoli are membrane-bounded structures present in the eukaryotic nucleus.
(b) The fibrils seen in electron micrographs of nucleoli contain DNA and RNA.
(c) The DNA of nucleoli carries the cell’s tRNA genes, which are present in clusters of multiple copies.
(d) A single nucleolus always corresponds to a single nucleolus organizer region (NOR).
(e) Nucleoli become heavily radiolabeled when radioactive ribonucleotides are provided to the cell.
(f) In animals and plants, the disappearance of nucleoli during mitosis correlates with cessation of ribosome synthesis.

At 20 Celsius degree, protein-Z binds DNA with a free energy of –7 kJ/mole. Protein Z has an unfolding free energy of 11 kJ/mole without ligand bound and 15 kJ/mole with ligand bound. Does the unfolded/denatured form of protein Z bind to DNA, and if so – what is the "Delta G" of binding of the unfolded form?
Reposting - What would the tertiary structure of the dipeptide Asp-Ser be if it was made into a polypeptide chain? (Would it form a beta pleated sheet, an alpha helix, etc) Why would it do this? What properties of this polypeptide causes this?
This sub part still needs to be solved - What would the tertiary structure of Pro-ala and Glycl-L-alanine be?
Calculating human genome
If 1.5 percent of the human genome consists of protein-coding sequences, and the entire genome has 3.2x10^9, how many codons are there in the human genome? Remember that a codon is three nucleotides in length.
