Is the chromatid double helix structure, or the chromsome?
versatilekamini Teacher Doctorate eNotes Editor Chromosomes are filamentous bodies which are typically present in the nucleus and which become visible during cell division. They are the carriers of the genes or units of heredity. The length of chromosomes varies from 1 micron to 30 microns. The chromosome includes the centromere, secondary constrictions, nucleolar organisers, telomeres and satellites. Under the light microscope the metaphasic chromosome appears to be made up of two subunits called chromatids. These are possibly twisted around each other. If the chromosomes are treated with trypsin to remove proteins, each chromatid is seen to consist of two subchromatids. Possibly the subchromatids represent the chromonemata.
