chromosomes duplicate before mitosis
The Chromosome go through 5 phases:
1. Interphase - the cell's chromosomes duplicate. the nucleolus is clearly visible ion the nucleus.
2. Prophase - the chromatid pairs are now visible and the spindle is beginning to form.
3. Metaphase - chromatid pairs are lined up in the center of the cell.
4. Anaphase - the chromsomes have seperated.
5. Telophase - in the final step, the cytoplasm is beginning to seperate.
The 2 new cells that were created, enter interphase and cell division usually begins again.
The chromosomes are duplicated before mitosis begins.

∙ 9y agoDuring the early stage of interphase, chromatin is loosely dispersed throughout the nucleus. Later on, when the chromatin starts replicating, it becomes condensed so that the chromatids will separate evenly.

Also, I'm swagalicious.

How many chromosomes would a cell have during metaphase 1 of meiosis if it has 12 chromosomes during interphase?
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
How does the number of chromosomes in metaphase of mitosis compare to the number of duplicated chromosomes in metaphase 2 of meiosis?
because in metaphase 2 of meiosis there are 2 different cells, which means the chromosomes duplicated
How many chromosomes are there in cells of humans after meiosis?
There are 23 chromosomes in a human cell following meiosis. Meiosis is sometimes called "reduction division". The first division of meiosis (meiosis I) halves the chromosome number. In humans, there are 46 chromosomes in the mother cell when it begins meiosis I. More precisely, there are 23 pairs, one of each pair having been inherited from each parent. This number (46 in humans) is the diploid number for the species. After meiosis, each cell has the haploid number (23 in humans), i.e. one of each chromosome in the set.
Are the chromosomes replicated or nonreplicated at the end of meiosis one?
In meiosis, for daughter cells are produced, each containing half the number of chromosomes of the parent cell.
What produces cells with half normal number of chromosomes?
Meiosis is a form of cell division that produces four daughter cells that are haploid (have half the number of chromosomes found in a normal/somatic cell). Meiosis is involved in sexual reproduction, and produces gametes (sperm and ovum/egg).

Does meiosis double the parental chromosomes number?
Meiosis 1
Meiosis reduce the number of chromosomes by?
by half.

Why reductional division or meiosis essential in organism?
Meiosis reduces number of chromosomes to one half . when two gametes fuse , it restores original diploid number of chromosomes .With out this diploid number of chromosomes could not be maintained .
Is meiosis is associated with haploid number of chromosomes?
Yes, the process of meiosis results in four daughter cells with a haploid number of chromosomes. In contrast, mitosis results in two daughter cells with a diploid number of chromosomes.
What happens to the chromosomes number by the end of meiosis?
The chromosome number at the end of meiosis is half of the parent cell
Process where the number of chromosomes is reduced by half?
Meiosis.
Does metaphase of mitosis meiosis 1 or meiosis 2 have the haploid number of chromosomes at the equator of the spindle?
meiosis 1
What is the process of division that results in the formation of cells with half the usual number of chromosomes?
The process of meiosis.
When do homologus chromosomes occur short answer please thankss?
Homologous chromosomes occur during meiosis. Meiosis reduces the chromosome number by half.
