Vrishaketu, son of Karna, fought on the side of Kauravas, but became very close to the Pandavas after the war. Later during the time of Pandavaâs Aswamedha Yaga, he fought alongside Arjuna against Babhruvahana.Vrishaketu shoots Babhruvahana into the air through a circle of arrows (Circa 1850). * * *.rishaketu, son of Karna, fought on the side of Kauravas, but became very close to the Pandavas after the war.

Through the microscope, the nucleolus looks like a large dark spot within the nucleus. A nucleus may contain up to four nucleoli, but within each species the number of nucleoli is fixed. After a cell divides, a nucleolus is formed when chromosomes are brought together into nucleolar organizing regions. During cell division, the nucleolus disappears. Some studies suggest that the nucleolus may be involved with cellular aging and, therefore, may affect the senescence of an organism.
