Nucleus

1. 2-The nucleus contains the DNA
 The largest single organized cell component, can be seen as a
distinct spherical structure, usually located near the center of
the cell
 Nucleus is surrounded by the nuclear envelope - a double
membrane which separates it from the rest of cell
 Nuclear membrane has nuclear pores that control entry and exit
of materials
 Contains the nucleolus - a darkened region where ribosomal
RNA is synthesized
 Contains chromosomes - consist of DNA wrapped around
proteins

2.  The nucleus houses the cell’s genetic material, deoxyribonucleic acid (DNA), which
has two important functions: (1) directing protein synthesis and (2) serving as a
genetic blueprint during cell replication.
