Chapter 5 Vocab

The division of the cell nucleus and it’s contents

The regular pattern of growth, DNA replication, and cell division that occurs in eukaryotic cells

Process that divides the cell cytoplasm

Long, continuous thread of DNA that consists of numerous genes and regulatory information

Protein that organizes chromosomes and around which DNA wraps

Loose combination of DNA and chromosomes that is present during interphase

One half of a duplicated chromosome

Region of the condensed chromosome that looks pinched

Repeating nucleotide at the ends of DNA molecules that do not form genes and help prevent the loss of genes

First phase of mitosis when chromatin condenses, the nuclear envelope breaks down, the nucleolus disappears, and the centrisomes and centrioles migrate to opposite sides of the cell

Second phase of mitosis when spindle fibers align the chromosomes along the cell equator

Third phase of mitosis during which chromatids separate and are pulled to opposite sides of the cell

A complete set of identical chromosomes is positioned at each pole of the cell. The nuclear membranes start to form, the chromosomes begin to uncoil, and the spindle fibers fall apart
