Cell Differentiation
Undifferentiated cells that become differentiated into 1 or more types of specialized cells.
What is Stem Cells?
A repeated pattern of growth, DNA duplication, and cell division that occurs in eukaryote cells.
What is Cell Cycle?
One long continuous thread of DNA that consists of thousands of genes and regulatory information.
What is Chromosomes?
The division phase of the cell cycle.
What is Mitosis?
Signals that come from outside of the cell. Ex: hormone, nutrients, etc.
What is External?
Cells found in adult bone marrow.
The growth phase of the cell.
What is Interphase?
A section of DNA that contains the instructions for making protein.
What is Gene?
Chromosomes condense and are visible as sister chromatids.
What is Prophae?
signals that come from outside of the cell. Ex: DNA inside of the cell.
What is Internal?
Cells that have never differentiated.
What is Embryonic Stem Cells?
Cell grows and makes proteins.
What is Gap 1 phase?
One-half of a duplicated chromosome.
What is Chromatid?
Spindle fibers connect to the centromeres of each sister chromatid.
What is Metaphase?
Critical point where "stop" and "go" signals can regulate the cycle.
What is Checkpoints?
Set of tissues working together for a common function.
DNA replication occurs, doubling the number of chromosomes.
What is Synthesis Phase?
Two Identical chromatids.
What is Sister Chromatids?
Sister chromatids separate, pulling away from each other and becoming individual chromosomes.
What is Anaphase?
Programmed cell death.
What is Apoptosis?
Group of cells working together for a common function
What is Tissue?
More cell growth and protein synthesis.
What is Gap 2 phase?
Ends of the DNA molecule.
What is Telomere?
Chromosomes decondense and start to look like chromatin again.
What is Telophase?
