In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

Answer:
The correct answer would be coagulation.
Coagulation refers to the process by which blood clots and prevent bleeding.
During this process, the blood thickens and changes into the gel from a liquid.
It ultimately leads to hemostasis which is defined as the first stage of wound healing.
It involves different clotting proteins and factors. One such protein is fibrinogen, a soluble protein which is converted into insoluble form fibrin. Fibrin with the help of platelets forms a stable thrombus.
