Telomeres are arms of chromosomes whose lenght determines the longevity of the cell in terms of continuation of mitotic division which is basic to continuing life.Chromosomes in turn are genetic codes which transmitt patterns for body protein synthesis for various functions and structures including continuing life.The nucleus of the cell is the location for genetic materilas called chromosomes and they are tightly wound except during cell division they unwound and then template replication by certain dna and Rna gyrases lead to duplcation of this materials hence new cells and tissue are produced.
