Quizplus · Accepted Answer

The Hayflick limit refers to the number of times a cell can divide in culture before reaching senescence, which is typically around 50 divisions for normal human cells. This phenomenon was discovered by Leonard Hayflick in the 1960s and is believed to be related to the shortening of telomeres (the protective ends of chromosomes) with each cell division.
