What is the function of kinetochores in cell division?
Kinetochores are protein structures that form on the centromere of chromosomes during cell division. Their main function is to attach to spindle fibers and help separate the chromosomes during mitosis and meiosis. This ensures that each daughter cell receives the correct number of chromosomes.
What phase do chromosomes move to the middle of the cell?
During metaphase, chromosomes align in the middle of the cell and attach to the spindle fibers. This alignment ensures that each daughter cell will receive the correct number of chromosomes during cell division.
What does Chromatin condense of?
Chromatin condenses into chromosomes during cell division in order to facilitate the orderly segregation of genetic material into daughter cells. This condensation helps ensure that each daughter cell receives the correct complement of chromosomes.
How do organisms with multiple linear chromosomes ensure accurate segregation during cell division?
Organisms with multiple linear chromosomes ensure accurate segregation during cell division through a process called mitosis. During mitosis, the chromosomes replicate and line up in the center of the cell before being pulled apart into two separate daughter cells. This ensures that each daughter cell receives the correct number of chromosomes, maintaining genetic stability and preventing errors in cell division.
How is the chromosome number maintained during cell division, specifically in the processes of mitosis or meiosis?
During cell division, the chromosome number is maintained through the processes of mitosis and meiosis by ensuring that each daughter cell receives the correct number of chromosomes. In mitosis, the replicated chromosomes are separated equally into two daughter cells, while in meiosis, the chromosomes are divided twice to produce four daughter cells with half the original number of chromosomes. This ensures that the chromosome number is maintained in the offspring cells.
What is the first thing chromosomes do in meiosis?
In meiosis, chromosomes replicate during interphase before the start of cell division. This process ensures that each daughter cell will receive the correct number of chromosomes.
Which structure connects the replicated chromosomes?
The centromere is the structure that connects the replicated chromosomes during cell division. It plays a crucial role in ensuring that each daughter cell receives the correct number of chromosomes.
When a cell with 23 chromosomes divides by mitotic call division both of the resulting daughter cells each have the maximum number of 23 chromosomes?
New Q. Answer is Yes. Remember, eukaryotic chromosomes exist in pairs.Ex-Q. Answer was: about meiosis and mitosis I will answer both:Mitosis is a form of cell division that results in the produced (or daughter) cells having the same number of chromosomes as the parent. In your example, a daughter cell resulting from mitotic cell division would have 23 chromosome pairs, just like its parent cell.Meiosis is a form of cell division that results in the produced (or daughter) cells having half the number of chromosomes present in the parent. In your example, a daughter cell resulting from meiotic cell division would have 23 chromosomes, half the number of the parent cell.
During cell division what moves chromosomes into position?
The spindle fibers, which are made of microtubules, help move the chromosomes into position during cell division. These fibers attach to the chromosomes and pull them apart to ensure each daughter cell receives the correct number of chromosomes.

What Maintains the chromosome number in the daughter nuclei?
During cell division, a structure called the mitotic spindle separates the duplicated chromosomes and ensures that each daughter cell receives the correct number of chromosomes. Additionally, checkpoints in the cell cycle regulate the progression of mitosis to ensure that the chromosomes are apportioned correctly and the daughter cells have the proper chromosome number.

This ensures that the chromosome number is maintained in the offspring cells.
What cell division do daughter cells have the same number of chromosomes as parent cell?
During mitosis, daughter cells have the same number of chromosomes as the parent cell. Mitosis is responsible for producing genetically identical daughter cells for growth and repair in multicellular organisms.
Why is it so important for all of the chromosomes to align on the metaphase plate during metaphase?
During metaphase, it is important for all chromosomes to align on the metaphase plate because this ensures that each daughter cell receives the correct number of chromosomes during cell division. This alignment helps to maintain the genetic stability and integrity of the resulting daughter cells.
