Human cell have 46 chromosomes before mitosis how many do they have after mitosis?
After mitosis, the cells will still have 46 chromosomes.Immediately after mitosis and cytokinesis (cell division), the cell has 46 chromosomes that have one chromatid (this is in G1). During S phase, the DNA replicates itself, so that now the cell has 46 chromosomes that each have two chromatids (this is where the doubling comes in). After G2, the cell enters mitosis, and these chromosomes divide, so that each half of the cell has 46 chromatids (this is where the division of DNA comes in). When this mitotic cycle finishes, the cell again has 46 chromosomes that each consist of one chromatid.
What two things happen during meiosis?
chromosomes split and the cell divides The above mentioned two things happen in mitosis also, so the correct answer would be - 1. Exchange of chromatin material by crossing over and 2. Reduction in the number of chromosomes to half.
When a cell divides through mitosis each daughter cell receives half of the parent cell's genetic code is it true?
No, when a cell divides through mitosis, each daughter cell receives an identical copy of the parent cell's genetic code, not just half. This ensures that the genetic information is preserved and passed on accurately.
How does the number in chromosomes in sex cells compare to the number of chromosomes in cells formed during mitosis?
it compares by 50% or by half of chromosomes because there are 23 sex cells and 46 chromosomes
How does mitosis differ from meiosis in terms of chromosome segregation?
In mitosis, chromosomes are duplicated and then segregated into two identical daughter cells, resulting in cells with the same number of chromosomes as the parent cell. In meiosis, chromosomes are duplicated but then segregated twice, resulting in four daughter cells with half the number of chromosomes as the parent cell.
Is a process where a parent cell divides into four sex cells with half the chromosomes?
mieosis or mitosis
How does meiosis 1 differ from mitosis in terms of the process of cell division?
In meiosis 1, the cell divides twice to produce four daughter cells with half the number of chromosomes, while in mitosis, the cell divides once to produce two daughter cells with the same number of chromosomes as the parent cell.
What are the differences between mitosis 1 and mitosis 2 in terms of their processes and outcomes?
In mitosis 1, the cell divides into two daughter cells with the same number of chromosomes as the parent cell. This process involves the separation of homologous chromosomes. In mitosis 2, the two daughter cells from mitosis 1 divide again to produce a total of four daughter cells, each with half the number of chromosomes as the parent cell. This process involves the separation of sister chromatids.
Why must mitosis and meiosis different?
During Mitosis a cell splits into two identical new cells. The chromosomes copy themselves and then the cell divides in half. In Meiosis the diploid divides itself twice rather than once to create four haploid cells. This is the creation of sex cells.
How many chromosomes of coleus having 24 chromosomes are present in each cell at the stage of mitosis or meiosis indicated?
At the stage of mitosis or meiosis, coleus cells with 24 chromosomes would have 24 chromosomes present in each cell. In mitosis, the cell divides into two daughter cells, each with the same number of chromosomes. In meiosis, a specialized cell division process, two rounds of division result in four daughter cells with half the number of chromosomes as the parent cell.
What phase of mitosis do chromosomes become half?
Chromosomes become half during anaphase of mitosis. Sister chromatids are separated and pulled to opposite poles of the cell, resulting in each daughter cell receiving a complete set of chromosomes.
What is it called when a cell reproduces?
When a cell reproduces, it is called cell division. This process can occur through mitosis, where the cell divides to create two identical daughter cells, or meiosis, which produces cells with half the number of chromosomes for sexual reproduction.
What is the function of the spindle?
Spindle fibers attach to the centromeres at metaphase and separate the splited chromosomes from each other.Spindle fibers are necessary in mitosis as they help in bringing half the number of chromosomes on each side of the cell, so that when the cell divides, the chromosomes are distributed equally in both the daughter nuclei.
What is meosis and mitosis?
Mitosis is a type of cell division that produces two identical daughter cells, each with the same number of chromosomes as the parent cell. Meiosis is a specialized type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell.

How many chromosomes are in the daughter cell at the end of mitosis?
There are going to be half the amount of the original chromosomes that were in each cell to begin with. So therefore there are going to be 4 chromosomes in each daughter cell at the end of mitosis..Actually there will be 2 chromosomes, in each daughter cell at the end of mitosis!
The nucleus is divided during?
The nucleus divides during cell division, specifically during the process of mitosis in somatic cells and meiosis in sex cells. Mitosis results in two identical daughter cells with the same number of chromosomes as the parent cell, while meiosis creates gametes with half the number of chromosomes to ensure genetic diversity.
