Cell Cycle phases
DNA is replicated in this phase of the cell cycle.
What is the S phase?
In this phase, sister chromatids are pulled apart.
What is anaphase?
Cells remain small due to a surface area to volume ratio issue that must be maintained. If the cell size increases, and the ratio gets smaller, then this results.
What is nutrients cannot enter and waste cannot leave?
This type of reproduction, unlike asexual reproduction, creates cells that are genetically unique from the parent cells.
What is sexual reproduction?
Checkpoints in G1 and G2 are regulated by these factors.
What are cyclins and kinases?
These two phases include cell growth, cell normal functioning and checkpoints.
What are G1 and G2?
The actual definition of mitosis is really about the division of this cell organelle.
What is the nucleus?
Cells divide at different rates because of this issue.
What is their use or what is how fast they get worn out?
Yeast can do this type of asexual reproduction.
What is budding?
These regulatory proteins use receptors on the cell membrane to activate and/or promote cell division.
What are growth factors?
Neurons, muscle cells and cardiac muscle get to a point of no more division once they are mature, then they are in this phase.
What is G0?
When cells align on the equatorial plate during metaphase, the spindle fibers attach to this region of the chromatids.
What is the centromere?
DNA coils around these proteins to form chromatin.
What are histones?
A star fish or flatworm can do this type of asexual reproduction in which a piece is broken off and forms a whole new organism.
What is fragmentation?
These cell types remain undifferentiated and can become various cells due to which genes are activated.
What are stem cells?
These structures form in the S phase of the cell cycle.
What are chromatids?
Cytokinesis, the division of the cytoplasm, differs in animal and plant cells. Animals form this due to pinching of the cell membrane.
What is a cleavage furrow?
Humans have this many chromosomes in each cell.
What is 46 or 23 homologous pairs?
Underground runners form in this type of asexual reproduction.
What is vegetative reproduction?
These four tissue types make up humans.
What are nerves, muscles, epithelium and connective tissues?
All body cells are referred to as this type of cell.
What are somatic cells?
Reforming a nuclear membrane, spindle dissolving and chromosomes becoming less compact describe this phase.
What is telophase?
These caps are on the ends of chromatids to minimize loss of genetic material during replication.
What are telomeres?
A student who had strep throat and did not take his/her antibiotics, became more ill because the germs replicated using this form a asexual reproduction.
What is binary fission?
This type of stem cell can become any type of specialized cell (the most versatile).
What is totipotent?
