Limestone.
It is a sedimentary rock composed of calcite and aragonite. It is used as a building material mainly because it is easily available and easy to work with.
Limestone is used in the manufacture of steel as it is the primary raw material that helps to remove impurities from the iron ore and produces waste matter that has low melting point and viscosity
Many human cells divide a finite number of times before going into permanent arrest, a phenomenon called Hayflick’s Phenomenon, which appears to be caused by the loss of telomeres.
Hayflick limit or Hayflick’s phenomena is defined as the number of times a normal cell population divides before entering the senescence phase.
Hayflick (1961) demonstrated that a population of normal human fetal cells divide in culture between 40 and 60 times before stopping.
This phenomenon is related to telomere length. Repeated mitosis leads to shortening of the telomeres on the DNA of the cell. Telomere shortening in humans eventually makes cell division impossible, and correlates with aging.
Telomeres are irrevocably shortened each time a cell divides. When the telomeres become too short, the cell can no longer divide.
