Cellular Growth
This occurs during cytokinesis
What is the cell divides creating a new cell?
First stage of mitosis
What is interphase?
Uncontrolled growth and division of cells
DNA
Trisomy 21
What is Down's Syndrome?
When considering volume and surface area of a cell, this increases more rapidly in a growing cell
What is volume?
Cell phase where chromosomes move towards opposite sides (poles) of cells
What is anaphase?
Unspecialized cells that can develop into specialized cells under the right conditions
What are stem cells?
This resides inside the nucleus when the cell is not undergoing cell division (looking for a word that is not DNA)
What is chromatin?
A cross of Yy x yy would produce what phenotypic ratio?
Y = purple, y = blue
2 purple : 2 blue
This occurs during interphase
What is the cell grows, carries out normal function, and replicates genetic material?
The stage during interphase where DNA replicates
S phase
Programmed cell death
What is apoptosis?
The half of a chromosome that divides during cell division
Sister chromatid
Mitosis happens in all cells (Y/N)
If not, which cells does it not occur in?
No, only somatic cells
Meiosis occurs in reproductive cells
Name something that limits cell size
What is transport of items in and out of the cell, communication between cells, (excetera)?
Cell cycle stage where two new nuclear membranes appear
What is telophase?
Unspecialized mass of cells that arise after fertilization
What are embryonic stem cells?
These attach to the centromere of chromosomes and pull each half apart during metaphase
What are spindle fibers?
These structures "pinch" the cell during cell division
What are microtubules?
Two purposes of cell division
What is keeps cell from getting too large, helps heal injuries, allows for growth, (excetera)?
Stage where cell prepares for the division of its nucleus
What is G2 (in interphase)?
If you had an adult muscle tissue stem cell, what types of tissue could you maintain/repair with these stem cells?
What is muscle tissue? (Adult stem cells can only be used on the same kind of tissue)
Structure that forms during cytokinesis in plant cells
What is the cell plate?
The cellular structure located on either pole of the cell during cell division that houses the centrioles
What is the aster?
