Some cancer-fighting drugs disrupt the cell cycle by preventing the formation of spindle fibers. Which specific phase of the cell cycle is such a drug most likely to disrupt?
M phase (apex)
Cell structures made of individual microtube fibers that are involved in moving chromosomes during cell division are called?
spindle fibers
What is Tumor cell?
What is a spindle cell tumor in the stomach?
What is the array called when spindle fibers radiate from the centrosomes?
mitotic spindle
Tiny contractile fibers that are within the cell?
Tiny contractile fibers that are within a cell are called spindle fibers. Spindle fibers separate the chromosomes during cell division.
Where does spindle fibers arises?
in the prophase stage of the cell cycle
What checks for cell damage during the Cell Cycle?
During the cell cycle CDK and Cyclin check for cell damage and oversized cells.
What is centride?
It is a T shaped structure with spindle fibers attached to it. The spindle fibers reach out to grab chromosomes during the cell cycle.
What happens to chromosomes during the stage of the cell cycle in which the nucleus divides.?
spindle fibers form a bridge between the ends of the cell
During what cell cycle phase is the spindle formed?
The spindle forms during prophase of mitosis or meiosis. The spindle is made up of protein fibers, which are microtubules of the cytoskeleton.
Some cancer-fighting drugs disrupt the cell cycle by preventing the formation of spindle fibers. Which specific phase of the cell cycle is such a drug most likely to disrupt?
M phase (apex)
When do spindle fibers attach to chromosomes?
Spindle fibers attach to chromosomes during mitosis. Specifically, they do so in the metaphase portion of mitosis, in preparation for the splitting of the cell.
During metaphase the centrometers attach to what structures?
In animal cells, during metaphase stage of the cell cycle, the centrioles attach to spindle fibers. These spindle fibers are also attached to the chromosomes which are now aligned at the metaphase plate.
What phase do chromosomes attach to spindle fibers?
In metophase and anaphase of the cell cycle.
What does a centride do?
A centride has spindle fibers attached to it that lengthen to reach the chromosomes. The centrides also move towards opposite ends of a cell around the middle of the cell cycle.
Fiibers extending from cell pole to cell pole are called what?
spindle fiber
Can you explain 'prophase' in one sentence?
Yes, prophase is a part in the cell cycle of mitosis where spindle fibers form and attach to chromosomes.
