How do mutations occur during mitosis?
reasorment of chromosomes can occur during meosis by crossing over
The events of prophase seem to be opposite of those that occur during what phase?
The events of prophase in mitosis, such as condensation of chromosomes and breakdown of the nuclear envelope, are opposite to those that occur during telophase, where chromosomes decondense, and the nuclear envelope reforms.
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.
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.
Which processes occur during distillation?
condensation
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.

What is the process Shortening and fattening of the chromosomes at the start of mitosis?
During the early stages of mitosis, chromosomes condense and shorten by coiling and folding, which helps to organize and compact the genetic material. This condensation allows the chromosomes to become more manageable and visible under a microscope. The shortening and thickening of the chromosomes help ensure that each daughter cell receives a complete and equal set of genetic information during cell division.
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.

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 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.
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.
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.
In mitosis or meiosis do doubled chromosomes pair to form tetrads?
In meiosis, doubled chromosomes (homologous pairs) pair to form tetrads during prophase I. This allows for genetic recombination to occur between homologous chromosomes. In mitosis, chromosomes do not pair to form tetrads as there is no crossing over between homologous chromosomes.
When phase of mitosis do chromosomes first become distinguishable from one another?
Chromosomes first become distinguishable from one another during prophase of mitosis, when they condense and become visible as distinct entities under a light microscope.
How many chromosomes are in cells formed during mitosis?
Cells formed during mitosis contain the same number of chromosomes as the parent cell - typically 46 chromosomes in human cells. This ensures that each daughter cell receives an identical set of genetic information.
