What is the process Shortening and fattening of the chromosomes at the start of mitosis?
During the early stages of mitosis, chromosomes condense and shorten by coiling and folding, which helps to organize and compact the genetic material. This condensation allows the chromosomes to become more manageable and visible under a microscope. The shortening and thickening of the chromosomes help ensure that each daughter cell receives a complete and equal set of genetic information during cell division.
How many chromosomes are are visible at the beginning of mitosis?
At the beginning of mitosis, each chromosome is duplicated and consists of two identical sister chromatids joined together. Therefore, the number of visible chromosomes at the start of mitosis is equal to the number of unique chromosomes in the cell. This number varies depending on the organism, but for humans, there are 46 visible chromosomes at the beginning of mitosis.
When during the cell cycle are chromotomes visible?
Chromosomes are visible during cell division, specifically during mitosis and meiosis. This is when the chromosomes condense and become more distinguishable. In interphase, the chromosomes are less condensed and not easily visible as individual structures.
The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
How many cells does mitosis start with?
Mitosis typically starts with one cell that has already gone through a round of DNA replication during the S phase of the cell cycle. This cell is called a somatic cell and contains a full set of chromosomes.

Condenses at the start of mitosis?
Chromosomes
In phases of mitosis how many chromosomes does the parent cell have during prophase at the start of mitosis?
During prophase at the start of mitosis, the parent cell has a diploid number of chromosomes, which consists of a complete set of chromosomes from both parents. This means that if a human cell has 46 chromosomes prior to mitosis, it would have 46 chromosomes during prophase as well.
How many pairs of chromosomes after mitosis?
There are 46 chromosomes after mitosis. It stays the same from the beginning.
How many chromosomes are are visible at the beginning of mitosis?
At the beginning of mitosis, each chromosome is duplicated and consists of two identical sister chromatids joined together. Therefore, the number of visible chromosomes at the start of mitosis is equal to the number of unique chromosomes in the cell. This number varies depending on the organism, but for humans, there are 46 visible chromosomes at the beginning of mitosis.
When do chromosome duplicate themselves during mitosis?
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
What stage of mitosis is occurring when the chromosomes start to align at the equator of the cell?
The stage of mitosis where chromosomes start to align at the equator of the cell is called metaphase. During metaphase, the chromosomes line up along the metaphase plate, ensuring that they will be equally divided between the two daughter cells during cell division.
Why is the nucleus start to disappear in early stage of mitosis?
so that the mitotic spindel can form and the chromosomes can get attched to the spindel
When do we have 46 chromosomes in meiosis or mitosis?
we have 46 chromosomes in Mitosis during interphase when the DNA doubles, but really Humans have 23 chromosomes. Meiosis is reproduction and goes through Mitosis twice but skips interphase the second time and creates gametes(sex cells) -Marina20
