What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
What stage of meiosis when chromosomes condense?
The chromosomes condense in prophase of mitosis. https://en.wikipedia.org/wiki/Mitosis#/media/File:Animal_cell_cycle-en.svg
When do chromosomes condense and become thicker rod-like?
Chromosomes condense and become thicker rod-like structures during the prophase stage of cell division, specifically during prophase I of meiosis and prophase of mitosis. This condensation is necessary for the chromosomes to be visible under a microscope and for proper segregation during cell division.
Each phase of mitosis?
The four stages of Mitosis is: Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. Metaphase:the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle fibers Anaphase:The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle fiber. Telophase: The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
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 difference between prophase mitosis and prophase meiosis?
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
Are homologous chromosomes present in both mitosis and meiosis?
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
What stage of meiosis when chromosomes condense?
The chromosomes condense in prophase of mitosis. https://en.wikipedia.org/wiki/Mitosis#/media/File:Animal_cell_cycle-en.svg
How does prophase you of meiosis differ from prophase of mitosis?
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
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.
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.
How are mitosis and meosis alike?
Mitosis and meiosis are both processes involved in cell division. However, mitosis results in two identical daughter cells, while meiosis results in four genetically different daughter cells. Both processes involve stages such as prophase, metaphase, anaphase, and telophase.
When do chromosomes condense and become thicker rod-like?

Strictly speaking mitosis and meiosis are divisions of the?
Mitosis is division of a cell. Consists of the stages Prophase, Metaphase, Anaphase, and Telaphase. Mitosis is part of the cell cycle. Meiosis is the division of a sex cell. Such as sperm or egg. Meiosis is unique because it goes through the stages twice. Prophase I, Prophase II, Metaphase I, and Metaphase II, etc.
