nucleus
nucleus In biology, membrane-bound structure that, in most
cells, contains the
chromosomes. As well as holding the genetic material, the nucleus is essential for the maintenance of cell processes. It manufactures the
rna used to build
ribosomes. Other RNA molecules carry the
genetic code from the
dna through pores in the nuclear membrane into the jelly-like
cytoplasm, where it is used as a template for
protein synthesis by the ribosomes. Cell division involves the splitting of the nucleus and
cytoplasm. Cells without nuclei include
bacteria and mammalian
erythrocytes (red blood cells).
