what is/are?
What is a skin cell?
any of the cells making up the skin.
In what phase of interphase would the skin cells DNA be replicated?
The S (synthesis) phase
In Mitosis what are the stages?
Prophase, Metaphase, Anaphase, and Telophase.
What happens in cytokinesis?
the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.
In which phase interphase does the checkpoint for DNA damage and can stop the cycle before entering the S stage of interphase?
G1 phase
What is an epidermis?
the surface epithelium of the skin, overlying the dermis.
In Interphase what are the three substages ?
The G1 phase, the S phase, and the G2 phase.
In which phase does the mitotic spindle lines up the chromosomes along the equator
Metaphase
How long does a human skin cell stay in cytokinesis?
22 hours
Why do checkpoints occur in the cell cycle?
So the cell can divide properly.
What are keratinocytes?
represent the major cell type of the epidermis, the outermost of the layers of the skin, making up about 90 percent of the cells there.
In what phase of interphase do skin cells prepare for mitosis
The G2 phase
In which phase do the chromosomes condense,envelope disappears, and spindle fibers attach to the chromosomes?
Prophase
What are the stages of cytokinesis?
Cytokinesis takes place in four stages: initiation, contraction, membrane insertion and completion.
In which stage of interphase does the checkpoint look for errors and growth?
S phase
What is the skin cell made of?
keratinocytes
In what phase of Interphase do Skins cells grow and perform normal functions?
The G1 phase
In which phase do the chromosomes separate and move towards the poles of the cell?
Anaphase
What happens if cytokinesis does not occur?
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells
Which phase does the checkpoint check for DNA replication?
G2 phase
What is stratum corneum?
it's the outermost layer of the epidermis and marks the final stage of keratinocyte maturation and development.
How many hours do skin cells stay in interphase?
Roughly 22 hours
In which phase does the nuclear envelope reforms and The cytoplasm starts to divide?
Telophase
The movements of cytokinesis seen in the cell are caused by the same spindle network that was responsible for the separation of the chromosomes.
Do the checkpoints fail when errors are detected?
Yes checkpoints usually fail when errors
