What Does It Start With? Review
When DNA and its attached proteins is spread out in the nucleus of non-dividing cells it is called ____. When it is scrunched up in dividing cells it is called ____.
-Chromatin -Chromosomes
When animal cells undergo cytokinesis they use a C __ __ __ __ __ __ __ F __ __ __ __ __ to split their cytoplasm, but plant cells use a C __ __ __ P __ __ __ __ because their cell wall keeps them from pinching.
-Cleavage Furrow -Cell Plate
Homologous Chromosomes
Same size, shape, and carry genes for the same traits but are NOT identical
Chromosomes are made of
two Chromatid arms joined in the middle by a Centromere
Interphase
Non-dividing phase of the cell cycle
Family of proteins that regulate the cell cycle in eukaryotic cells
Cyclins
DNA is copied during
Synthesis
Anaphase
The chromatid arms seperate and move to opposite ends of the cell.
When nerve cells are in G0 ____.
They stop dividing
Metaphase
Chromosomes line up in the middle of the cell
Centrioles are made up of ____.
Microtubules
Centrosome
Region near the nucleus where the centrioles are found that helps organize the spindle fibers during cell division
Meiosis
A type of cell division that results in four daughter cells each with half the number of chromosomes of a body cell
Bacteria divide by a process called ____.
Binary Fission
The disease in which the one of the body's own cells lose the ability to control cell division
Cancer
The repeating steps a cell goes through during its lifetime are called the C __ __ __ C __ __ __ __.
Cell Cycle
Mitosis
Cell division that results in two identical daughter cells
Prophase
Chromatin condenses into Chromosomes, the Centrioles and Spindle Fibers pull the Chromosomes and the Nuclear Membrane and Nucleolus disappear.
The spread of cancer cells to a new location in the body is called ____.
Metastasis
Cell division in eukaryotes consists of two parts:
Mitosis (Divides the Chromosomes) and Cytokinesis (Divides the Cytoplasm)
Telophase is also called ____.
Reverse Prophase
