Inside the nucleus in eukaryotic cells. In the cytoplasm in prokaryotic cells.
it happens in the nucleus
in the nucleolus NO it is not nucleus the nucleolus is in charge of making the what i call "somes" the ribosomes and the chromosomes.
The actual duplication of chromosomes takes place during synthetic phase of the cell cycle.
The cells of all living organisms
Interphasr
DNA replication occurs during the S phase of interphase, which is the phase that precedes mitosis. In this phase, the DNA molecules in the cell's nucleus are duplicated, resulting in two identical copies of each chromosome.
Replication does not take place during mitosis. It takes place before meiosis begins.
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
Mieosis takes place twice. Mitosis takes place only once
DNA replication is the process where DNA duplication takes place. DNA polymerase enzyme take part in the catalysis of new DNA synthesis. It is an important step to happen before mitosis.

Replication does not take place during mitosis. It takes place before meiosis begins.
the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes
Nuclear division by mitosis or meiosis
centromere is place at which spindle fibers are attached if the centromere is lost then chromosome will lose its point for the attachement of the spindle fiber and then will not be able to take part in mitosis. chromosome is usually lost in this case.
Prophase is one of the stages in the process of mitosis, the stages of mistosis are : 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase. So metaphase, anaphase, and telophase are what happends in mitosis and does not happen in prophase. And what happens in prophase that does not in mitosis is that the sister chromatids that were formed during interphase have shortened and thickened and are now visible with a light microscope.
Edgebono Utoosis
Mitosis takes place in meristematic cells.
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
Mitosis occurs within the nucleus as chromosomal replication and the cytoplasm where organelles are divided and the cell itself divides.
Mieosis takes place twice. Mitosis takes place only once
