Mean marrow dose is used to estimate, on a population basis, the risk of one late effect of radiation, which is _______________.

Proteasome inhibitors are used to treat some types of cancer. These inhibitors will directly affect which type of gene expression regulation?

Doses below the maximum permissible dose should not produce significant radiation effects.

Genetically significant dose:A. is estimated only through large-scale studiesB.  is 0.2 mGyt/yrC. is a high dose that is expected to cause measurable responses

In typical blood vessels, the alpha smooth muscle actin (aSMA) gene is highly expressed in the smooth muscle cell layer but not in the endothelial cells that line the vessels.  Compare the aSMA gene in smooth muscle cells and epithelial cells in terms of: A.  Likely modifications in the regulatory regions of the aSMA gene in the two cell types. Briefly explain your reasoning.  (4 points) B.  Likely positions of the aSMA gene in topological associated domains and/or lamina-associated domains in the two cell types. Briefly explain your reasoning.  (4 points)

Secondary protective barriers:

Chromosomal translocations are proposed to cause cancer-associated changes two to three orders of magnitude faster than would be expected from mutation alone. How can chromosomal translocations accomplish in a short time what mutation is not likely to accomplish over many years?

Which of the following regulatory molecules function in transcriptional regulation of gene expression?

In the distribution of bone marrow in adults, the ________________ has the lowest percentage of bone marrow.

Check the “yes” box if you submitted a 4th of July picture with you in it to Clinton. You must be in the photo for it to count.
