Frain 1 Jack Frain Timothy Wanninger Biology Honors 20 September 2016 How Cell Nuclei Squeeze Into Small Spaces “How Cell Nuclei Squeeze Into Tight Spaces” by Asier Joya explains how cells are able to squeeze through tight nooks and crannies in our body or the environment, and then return to it’s original shape, with a specific emphasis of the cell’s nucleus. The secret is in a protein called fascin, which sits on the nuclear envelope and binds to structures to add stability. This protein is high in concentration in cancer cells because they use it to better navigate through tissue during invasion. The last unit we covered as a class was on the cell and it’s organelles. The largest organelle in the cell is the nucleus. It contains Deoxyribonucleic Acid (DNA), a nucleolus (concentrated DNA), and a nuclear envelope. The nucleolus is where ribosomes are created in the cell. We learned about all this in Biology during the last unit. The author of the journal is very unbiased in her research.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
