Definition
| Exists in eukaryotic cells with primary function of storing DNA and allows for transcription of DNA to RNAs that function as building blocks of cells. |

Definition
| Inner Phospholipid Bilayer. Defines nucleus. Outer membrane is continuous with ER. |
|

Term
|
Definition
| 100 to 1000 nuclear pores all over. Nuclear Pore Complex: gated transport, standard nucleus traffic cop of proteins that plugs nuclear pores thats shut unless need for transport. |
|
|
Term
|
Definition
| Just under inner phospholipid bilayer is strong scaffold made of intermediate filaments. These make up actual structure of nuclear envelope. Breaks down during prophase and proteins that make up nuclear lamina get phosphorolated and fibers get phosphorolated allowing membrane to fall apart. |

Term
|
Definition
| Brush pile of intermediate filaments that add to structure.Centrosome outside of nucleus and acts as site where microtubules in cell are built (not part of nucleus, outside).Regulates # microtubules in cell found in close proximity to nucleus creating cage of microtubules around nuclear envelope. |

Definition
| Chromatin:Packaged DNA making DNA accessible. Heterochromatin:dark area, condensed/not active areas. Euchromatin: light region, actively used. |

|
Definition
| 3.2*10^9 base pairs (~30,000 genes). 300 unique genes compared to mice. 2% unique genes compared to chimps. Humans have complex to cause high variety from comparative system genome. Refers to sum total of DNA in cell. |
