In it, all the most important things happen, namely, the doubling of the chain of DNA and other structures, as well as the synthesis of a large amount of protein. The period in which cells endowed with nuclei perform direct preparation for division is called interphase. The very first phase of mitosis is actually thepreparation for cell division. This period is called "cell cycle" in biology. The result of this is the mandatory multiplication of the genetic basis of one cell in two by duplicating the DNA, so that the mother cell subsequently gives life to two children.Īll life cells can be concluded in the period from the formation of the daughter to its subsequent division in two.
Each of them includes several actions inside the cell. The biological significance of mitosis would be muchless if the division of cells was not the essence of most of the biological processes taking place on our planet. Without this, it is impossible to continue life on Earth, increase the populations of unicellular organisms, it is impossible to develop and continue the existence of a large multicellular organism, it is also impossible to reproduce sexually and develop a new life from a fertilized egg. The ability of cells to share is their most important function, the fundamental one. It is difficult to imagine even the unimagined, what role the process of simple division of cells in the organism plays in the vital activity. The biological significance of mitosis is very high.
