WebChromosomes appear as long thin threads at the interphase called chromatin. DNA is wrapped around the histone octamer to form a nucleosome, which is the repeating unit of chromatin thread. Chromatin fibres coil and condense further to form chromosomes at the metaphase. The structure of chromosomes is mostly studied at mitotic metaphase. WebChromosomes measure between 10 and 20 microns. Each chromosome has a characteristic shape and size . However, they tend to an X-like shape (in eukaryotes) or a circular shape (in prokaryotes).
