What else can I help you with?
When do the centromeres split and form the chromatids?
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.
What is the stage of mitosis when spindle fibers attach to the centromeres of sister chromatids?
The stage of mitosis when spindle fibers attach to the centromeres of sister chromatids is called metaphase.
Do plant cells have centromeres?
Yes, plant cells have centromeres. Centromeres are specific DNA sequences located on the chromosome where the kinetochore assembles during cell division to help in the separation of chromosomes. These structures are essential for the proper alignment and segregation of chromosomes during mitosis and meiosis.
Which phase of the cell cycle does the centromeres split?
The centromeres split during the anaphase stage of mitosis. This is when the paired sister chromatids are pulled towards opposite poles of the cell by the spindle fibers.
Cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called?
The cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called spindle fibers or mitotic spindles. They help in the separation of chromosomes during mitosis or meiosis by attaching to the centromeres.
What are the centromeres slip and the chromatids separate?
During anaphase in mitosis or meiosis II, the centromeres split, allowing each sister chromatid to be pulled to opposite ends of the dividing cell by the spindle fibers. This leads to the separation of the chromatids into individual chromosomes, ensuring that each daughter cell receives a complete set of genetic material.
Where are chromatids attached?
Centromeres
Are genes composed of centromeres?
No
How might spindle microtubules assist in the process of splitting centromeres?
Spindle microtubules attach to the centromeres, facilitating their alignment and separation during cell division. The microtubules help pull the duplicated chromosomes apart by exerting force on the centromeres, ensuring that each daughter cell receives the correct number of chromosomes. This process ensures equal distribution of genetic material during cell division.
Begins with the separation of centromeres?
Anaphase
What releases spindle fibers?
centromeres
When do the centromeres split and form the chromatids?
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.
What material would you use to represent the cell wall?
When I made a model of a cell, I used MODEL MAGIC clay for the cell wall.
I am doing an experiment and i need to know what material can represent my experiment has a tough material?
metal
What is dicentric chromosomes?
A chromosome that has two centromeres.
What structure holds the individual chromatid?
Centromeres.
During prophase what structures are held together by the centromeres?
The sister chromatids are held together by the centromeres. Each chromosome is made up of two sister chromatids.
