i dont know, this is my question that i have no answer
reasorment of chromosomes can occur during meosis by crossing over
No, chiasmata do not occur in mitosis. Chiasmata are structures that form during meiosis, specifically during prophase I, as a result of crossing over between homologous chromosomes. Mitosis does not involve homologous chromosomes pairing up and exchanging genetic material like in meiosis.
Yes, condensation of the chromosomes occurs during mitosis. This process involves the chromosomes becoming more tightly coiled and condensed to facilitate segregation of genetic material into the daughter cells.
The fastest stage of mitosis is prophase, where the nuclear envelope breaks down and the chromosomes condense. This stage sets the foundation for the subsequent stages of mitosis to occur efficiently.
In order for mitosis to occur, eukaryotic chromosomes need to be properly replicated and condensed. Each chromosome must consist of two sister chromatids held together at the centromere, ensuring that genetic material can be evenly divided between the two daughter cells. Additionally, the chromosomes must be aligned correctly at the metaphase plate during mitosis to facilitate accurate separation. Proper functioning of the spindle apparatus is also crucial for this process.

No, synapsis does not occur in mitosis. Synapsis is the pairing of homologous chromosomes during meiosis, not mitosis. In mitosis, replicated chromosomes line up and separate into daughter cells without the pairing of homologous chromosomes.
No, chiasmata do not occur in mitosis. Chiasmata are structures that form during meiosis, specifically during prophase I, as a result of crossing over between homologous chromosomes. Mitosis does not involve homologous chromosomes pairing up and exchanging genetic material like in meiosis.
Structures of mitosis include chromosomes, chormatids, centrioles, chromosome, and spindles. basically the things that are made and used for mitosis to occur
something very important
Replication of DNA and separation of sister chromosomes.
Yes, nondisjunction can occur during mitosis. Nondisjunction is the failure of chromosomes to separate properly during cell division, leading to an abnormal distribution of chromosomes in the daughter cells. This can result in genetic disorders such as Down syndrome.
Condensation and shortening of chromosomes occur during the prophase stage of mitosis. In prophase, the chromatin fibers condense and coil tightly to form distinct, visible chromosomes.
Yes, condensation of the chromosomes occurs during mitosis. This process involves the chromosomes becoming more tightly coiled and condensed to facilitate segregation of genetic material into the daughter cells.
The uncoiling and decondensing of the chromosomes occurs during telophase of mitosis. In this phase, the nuclear envelope reforms around the separated chromosomes, and the chromatin (uncoiled chromosomes) begins to relax back into its less condensed state.
During prophase I of meiosis, homologous chromosomes pair up and undergo crossing over, where segments of DNA are exchanged between them. This does not occur during prophase of mitosis, where homologous chromosomes do not pair up or undergo crossing over.
