Cell Cycle
The first phase of the cell cycle
What is interphase?
Chromatin is found in which DNA?
Eukaryotic DNA
Does sexual reproduction need a mate?
Yes
What regulates the cell cycle?
Regulatory proteins, cyclins, and apoptosis
What's a popular disorder where cells lose the ability to control growth
Cancer
How many phases are in mitosis?
4 phases
[Prophase, metaphase, anaphase, telophase].
Linear chromosomes found within a nucleus
Eukaryotic cells
What organism does asexual reproduction?
Plants, body cells, starfish, and some bacteria.
When do MPF cyclin levels drop?
During the M phase
How does normal cells differ from cancer cells?
Cancer cells have a darker nucleus and are shaped more abnormally compared to the circular normal cells.
What do spindle fibers do?
Spindle fibers pull sister chromatids apart towards opposite sides of the cell.
Chromosomes are attached to the cell membrane, what type of DNA is this?
Prokaryotic DNA
Offsprings may be less well adapted to current conditions
Sexual reproduction
What is apoptosis programmed to do?
It's programmed to do cell death and possibly kill healthy cells.
What are the three treatments that can be used for uncontrolled growth?
Surgery, radiation, and chemotherapy
What is G2 known for in the cell cycle.
G2 is known for more cell growth and duplication of organelles. It prepares for the division.
Which asexual reproduction is simpler and quicker?
Binary fission
Offsprings are being produced in a short period of time, what type of reproduction is this?
Asexual reproduction
What are cyclins mainly known for?
Regulating the timing of cell division in eukaryotic cells.
Doctors found a tumor that doesn't spread to the surrounding tissue. What type of tumor did they find?
Benign tumors [Noncancerous]
A cell enters cytokinesis and instead of splitting, a cell plate is created between the two daughter cells. What cell is this?
A plant cell.
A scientist was studying DNA and found that there were histone proteins and nucleosomes in it. What DNA is his studying?
Eukaryotic DNA
Between asexual and sexual reproduction, which shows genetic diversity being beneficial in changing environments?
Sexual reproduction
Doctors noticed an injury and decided to stimulate proteins with growth factors to speed up cell division. What kind of regulator is this?
External regulators
A patient is facing melanoma, what treatment should they use?
Surgery
[Unless it's very small, it can be cut out]
