What phase of mitosis does the uncoiling and decondensing of the chromosomes occur?
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.

Does synapsis occur in mitosis?
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.
Can nondisjunction occur during mitosis?
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.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
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.
Must spores occur in mitosis?
Spores are produced through a specialized form of cell division called meiosis, not mitosis. Meiosis involves two rounds of cell division that results in the formation of haploid spores with half the number of chromosomes as the parent cell. These spores will eventually undergo mitosis to form new multicellular organisms.
Does mitosis occur in humans?
Yes, mitosis occurs in humans. It is a process of cell division that produces two identical daughter cells with the same number of chromosomes as the parent cell.
Does longitudinal splitting of chromosomes occur in mitosis?
No, longitudinal splitting of chromosomes does not occur in mitosis. During mitosis, chromosomes condense and align along the metaphase plate before being separated into two daughter cells. Longitudinal splitting can occur during meiosis I to produce haploid daughter cells.
How do mutations occur during mitosis?
reasorment of chromosomes can occur during meosis by crossing over
Does synapsis occur in mitosis?
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.
Does chiasmata occur in mitosis?
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.
What is the structure of mitosis?
Structures of mitosis include chromosomes, chormatids, centrioles, chromosome, and spindles. basically the things that are made and used for mitosis to occur
What are the two process that closely occur in mitosis?
Replication of DNA and separation of sister chromosomes.
What important changes occur to the chromosomes and the nucleus of prophase of mitosis?
something very important
What phase does condensation and shortening of chromosomes occur?
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.
Does condensation of the chromosomes occur during mitosis?
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.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
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.
What is the fastest stage of mitosis?
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.
Must spores occur in mitosis?
Spores are produced through a specialized form of cell division called meiosis, not mitosis. Meiosis involves two rounds of cell division that results in the formation of haploid spores with half the number of chromosomes as the parent cell. These spores will eventually undergo mitosis to form new multicellular organisms.
