Immortal Cells Jordan Stanton The hayflick limit was introduced by Leonard Hayflick in the 1970’s. His theory states that most types of human cells have a certain limit to the amount of times they can divide, or reproduce. For instance, if a cell has a hayflick limit of 50, it will divide 50 times and then it will become senescent, or weak and on the verge of death. What makes immortal cells so unique is their lack of a hayflick limit which means they can divide as many times as they wish and still remain alive. The only way to get rid of an immortal cell is to kill it. Some examples of immortal cells or cells that reflect no hayflick limit are bacteria cells, cancer cells, sperm cells and ova cells. Inside every cell there is a nucleus and contained in that nucleus is chromosomes. At the tip of each chromosome there is a telomere. The function of these telomeres is to keep the ends of chromosomes from sticking together, and from sticking to other present chromosomes.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
