Cell Cycle
Cell division in prokaryotes.
What is Binary Fission?
The alignment of the chromosomes at the center of the cell.
What is metaphase?
This molecular decision-making process commits a cell to a particular developmental pathway.
What is determination?
These types of cells do not use cell migration during morphogenesis.
What are plant cells?
These cells are capable of continued division and can also give rise to differentiated cells.
What are stem cells?
The primary growth phase of the cell.
What is Gap Phase 1 (G1)?
The shortest stage of mitosis.
What is Anaphase?
Cells initiate developmental changes by using __________ to change patterns of gene expression.
What are transcription factors?
_________ are a large gene family, with over 80 members identified in humans.
What are Cadherins?
The centrioles extend a radial array of microtubules toward the nearby plasma membrane when they reach the poles of the cell.
What are asters?
_________ requires the duplication of the genome, its accurate segregation, and the division of cellular contents.
What is the cell cycle?
Ribosomal RNA synthesis ceases in this stage.
What is Prophase?
Cells become committed to following a particular developmental pathway in one of these two ways.
What are cell to cell interactions; and what is differential inheritance of cytoplasmic determinants?
Animals regulate these processes to achieve morphogenesis.
What are the number, timing, and orientation of cell divisions; cell growth and expansion; changes in cell shape; cell migration; and cell death?
___________ is is the product of changes in cell structure and cell behavior.
What is morphogenesis?
At any given time, most of the cells in an animal’s body are in this phase.
What is G0 phase?
In this stage, the condensed chromosomes become attached to the spindle by their kinetochores.
What is Prometaphase?
The formation of the notochord and mesenchyme is due to _______ ?
What are inductive cell interactions?
In C. elegans, there is always a specific number of cells that always die during development in a predictable and reproducible pattern. The number is ______?
What are 131 cells?
During the course of development, some cells are programmed to die shrivel and shrink in a process called __________.
What is apoptosis?
The events that occur during the G1, S, and G2 phases are very important for the successful completion of mitosis and they are collectively referred to as ________?
What is interphase?
Two basic mechanisms of congression that move the chromosomes during prometaphase.
What are the assembly and disassembly of tubulin subunits and motor proteins?
These are four types of stem cells.
What are totipotent, pluripotent, multipotent and unipotent?
These three genes control apoptosis in C. elegans.
What are CED-9, CED-4, and CED-3?
_________ are attached to actin filaments of the cytoskeleton and protrude out from the cell surface in pairs, like two hands.
What are integrins?
