semi-fluid liquid in which numerous orgnalles are suspended in the nucleus
cytoplasm
entire region between the nucleus and the membrane
nucleus
contains a eukaryotic cell's genetic library
nuclear envelope
a double membrane perforated by pores that regulate the movement of large macromolecules between the nucleus and cytoplasm
nuclear lamina
lines the inner membrane with a layer of protein filaments
chromatin
organized dna whitin the nucleus
chromosome
composed of chromatin, visible only when coiled and condensed
