Vocabulary
Process in which a cell divides into two new daughter cells
Cell division
Most cell growth occurs in this phase, where the cell increases in size
G1 phase
Threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next
Chromosome
During this phase of cell division, the chromosomes line up in the middle with the spindle fibers attaching to them
Metaphase
An unspecialized cell that can give rise to one or more types of specialized cells
Stem cell
Type of reproduction involving a single parent that results in offspring that are genetically identical to the parent
Asexual reproduction
DNA replication occurs during this phase
S phase
One of two identical "sister" parts of a duplicated chromosome
Chromatid
During this phase of cell division, the genetic material condenses into chromosomes & the spindle fibers are forming
Prophase
Uncontrolled cell growth, where cells are growing and dividing more than they should, can lead to what disorder?
Cancer
Process of programmed cell death
Apoptosis
Cell division occurs in this phase
M phase
Region of a chromosome where the two sister strands of a duplicated chromosome attach
Centromere
Anaphase
Differentiation
Stage of early development in mammals that consists of a hollow ball of cells
Blastocyst
Important molecules and organelles needed for the M phase grow during this phase
G2 phase
Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
Chromatin
During this phase of cell division, the cytoplasm is split to form two daughter cells
Cytokinesis
The inner cell mass of the blastocyst becomes?
Cells that are able to develop into any type of cell found in the body (including cells that make up extraembryonic membranes & placenta)
Totipotent
Period of the cell cycle between cell divisions in which the cell grows
Interphase
True/False - The X-like chromosomes are duplicated chromosomes
True
During this phase of cell division, a nuclear envelope reforms around the two separate groups of chromosomes
Telophase
Adult stem cells are considered: totipotent, pluripotent, or multipotent? (Hint: adult blood stem cells only become blood cells)
Multipotent
