Assume you are analyzing the cell division process (mitosis and cytokinesis) in two individuals - a 10 year old male human and a 50 year old male human. Contrast the purpose of cell division and the locations where you would find cell division in these two individuals.

In the original implementation of PSI-BLAST, the algorithm performed a multiple sequence alignment and deleted all but one copy of aligned sequence segments having ≥ 98% identity. In a recent modification, the program now purges segments having ≥ 94% identity. What do you think would happen if this percentage were adjusted to ≥ 75% identity. How could you test this idea in practice?
