What else can I help you with?
Is the first phase of mitosis in which chromosomes condense and spindle microtubules begin to form.?
the phase of mitosis when chromosimes are ligned in the middle of the cell
Why does mitosis have to have microtubules in order to occur?
Mitosis require microtubules because they bind to the chromosomes and pull them to each pole of the cell. The cell can then divide with the respective chromosomes on separate halves of the cell.
What phase do microtubules attach to kinetochores?
Microtubules attach to kinetochores during the prometaphase stage of cell division. This attachment is essential for the proper alignment and segregation of chromosomes during mitosis.
When do microtubules attach to kinetochores?
Microtubules attach to kinetochores during prometaphase of mitosis, forming the mitotic spindle apparatus. This attachment is crucial for proper chromosome alignment and segregation during cell division.
During mitosis chromosomes are moved and separated through the use of spindles composed of?
microtubules. These microtubules are formed from the centrosomes and attach to the chromosomes at their kinetochores. As the microtubules shorten and lengthen, they pull the chromosomes apart, ensuring that each daughter cell receives the correct number of chromosomes.
What is responsible for moving chromsomes during mitosis?
microtubules or cytoskeleton (as in centrioles)
What stage of mitosis do Chromsomes first become visible?
prophase
How many chromsomes will be in the new body cells formed from mitosis?
46 in humans
Where do microtubules attach to chromosomes during mitosis?
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
What are spindle fibers composed of?
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
In the telophase stage of mitosis microtubules gather along the cell's equator The purpose of these microtubules is to?
D. assemble materials that will form the new cell wall.
What organelle has two short microtubules at right angles and have an active role in mitosis?
centriole
Is the first phase of mitosis in which chromosomes condense and spindle microtubules begin to form.?
the phase of mitosis when chromosimes are ligned in the middle of the cell
What is the function of the centriole pair?
It organizes the microtubules in mitosis. The microtubules move the chromosomes around the cell during mitosis, most importantly lining the chromosomes up at the metaphase plate in metaphase so that they can split up into the two daughter cells.
