A I think but can you get a better picture of the questions
If the original cell had 52 chromosomes then the two daughter cells produced would be identical, both with 52 chromosomes
Cation-exchange chromatography is used when the molecule of interest is positively charged, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. So, the amino acids with negative charge will elute the first. Glutamate, leucin, arginine is the order of elution because of their pI values ~3, ~6 ~10.
It helps classify animals according to their needs.
Hope this helps!
