Chambers CH 5. SEC.1-2

Cell cycle

the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells

Mitosis

The divisor of the nucleus and its contents

Cytokinesis

the process that divides the cell cytoplasm

Chromosome

A lone continuous thread of DNA that consists of numerous genes along with regulatory information

Histone

Each chromosome is associated with a group of proteins call this _________

Chromatin

A loosed combination of DNA and protein

Chromatid

one half of a duplicated chromosome

Centromere

Sister chromatids are held together at this point

Telomere

Repeated nucleotide at the end of the DNA molecule that don't form genes and help prevent the loss of genes

Prophase

Chromatin condenses into tightly coiled chromosomes. The nuclear envelope breaks down, the nucleolus disappears, and the centrioles began to migrate to opposite sides of the cell.

Metaphase

phase of mitosis when chromosomes line along the center of the cell equator

Anaphase

sister chromatids separate from each other. The spindle fibers begin to shorten, pulling the sister chromatids to opposite sides of the cell.

Telophase

A complete set of identical chromosomes is positioned at each pole of the cell. The nuclear membrane starts to form.
