chromatin
dense mass if material within the nucleus that is composed of individual chromosomes.
chromosome
structure that carries the genes; composed of protiens and DNA

structure of the cytoskeleton in eukaryotes; composed of actin and myosin, it provides structural support and assist cell movement.
microtubule
structure of the cytoskeleton in eukaryotes that helps certain organells move within the cell.
