Each of the following statements describes a type of column chromatography. Sort the statements to the type of chromatography they describe. If a statement can describe all of the types, place that statement in the "All" category. (Note that size-exclusion chromatography may also be called gel-filtration or molecular exclusion chromatography.)
Categories: Size-exclusion Chromatography, Affinity Chromatography, Ion-exchange Chromatogrpahy, and All Statements:
Separate molecules by size.
Separate molecules by charge.
The stationary phase has a covalently bound group to which a protein in the mobile phase can bind.
Uses a mobile phase and a stationary phase to separate proteins.
The stationary phase contains cross-linked polymers with different pore sizes.
Can separate molecules based on protein-lignand binding.
The stationary phase may contain negatively or positively charged groups.

Consider you could micro-inject the cytochrome c within the cytosol of the wild-type cells and of cells which were doubly defective for Bax and Bak.
Compute the surface-area-to-volume ratio of a cube whose sides are 100 um in length to estimated the surface-area-to-volume ratio of the fern spore cell.
You have a 10x enzyme buffer that you are to use in a particular reaction. The total volume of the reaction is 30 micro liters. Determine how much of the 10x buffer should you add so that the final concentration of buffer in the reaction is 1x?
Diploid nuclei of the ascomycete, Neurospora crassa, contain 14 chromosomes. A single diploid cell in an ascus will undergo one round of meiosis, followed in each of daughter cells by one round of mitosis, producing a total of eight ascospores.
Why is the frequency of the sickle-cell gene different in North America versus Africa. Now what is your definition of male and female? This is a 26-year-old female with congenital adrenal hyperplasia. What do you say.
