설명
It is the chromatin threads that carry the genes in the cell. Chromatin is a complex of DNA and proteins that exists in a loose, thread-like form when the cell is not dividing. During cell division, this chromatin condenses to form chromosomes, which are more visible under a microscope. Genes, the functional units of heredity, are located on these chromatin threads.
