A sample contains two proteins, Protein A (pI 5.9) and protein B (pI 7.8).
Could you design an ion exchange chromatography method to separate these two proteins? (Please specify anion or cation exchange column, mobile phase, and binding/elution strategy?
Describe three ways in which enzyme activity levels in a cell can be regulated. Include at least one example inwhich the substrate itself is involved in regulation, and at leastone in which a non-substrate molecule is involved. For asubstrate/enzy..

a hypothetical human trait is controlled by a single gene locus. four alleles have been identified:a,b,c,d. alleles a,b,c, are all codominant; allele dis recessive to all other alleles. how many phenotypes are possible? how many genotypes are poss..
Sometimes, we see an ELISA plate in which every well turnsyellow upon the addition of substrate. Can you think of onetype of error that would result in this finding? What do youpredict would happen if the substrate were added in acid solution?
Zebrafish are increased in fish tanks with one family each tank. The mutation spadetail is a recessive lethal. A stock tank for spadetail was made by crossing two carriers.
In a cross of AABbCcdd x AaBbccDd what proportion of offspring will have the genotype of AABBCcdd? Please explain.
How will the signaling of a neuron be affected if the voltage- gated sodium channels open at a more negative membrane potential? How will the excitability of a neuron be affected by sodium channels that open at more positive membrane potentials?
Consider two gene loci in the mouse, locus 1 and locus 2. Each locus is on a different, nonhomologous autosomal chromosome . Alleles at locus 1 influence fur color.
