A nucleus is signals the rest of the cell that the cell is ready to undergo meiosis, in which case the chromosomes begin to condense with the help of histones, which is the beginning of prophase I of meiosis.

WHEN DO Chromosomes decondense into diffuse chromatin?
At the beginning of Prophase 1 during meiosis. It occurs in a sub-stage of Prophase 1 called Leptonema.
What changes in the chromosomes occur during meiosis?
waht changes in the chromosomes occur during meiosis
What is the prophase 1?
Prophase I is the stage in meiosis in which homologous chromosomes pair up. During this time, chromatids from the homologous pairs cross over and exchange segments with one another.
In what stage of mitosis does the chromatin coil and condense to form deeply staining bodies?
The chromosomes condense during prophase, the first stage of both mitosis and meiosis.
Describe the two stages in meiosis?
there are actually four stages or phases in meiosis: prophase, metaphase, anaphase and telophase. Within prophase there is the leptotene stage where individual chromosomes condense into strands within the nucleus, the zygotene stage where the chromosomes line up with each other into homologous chromosomes, the pachytene stage where the nonsister chromatids exchange genetic information over regions of homology, the diplotene stage where the chromosomes start to separate and uncoil a little to allow some transcription of DNA, and the diakinesis stage where the chromosomes condense further and the meiotic spindle begins to form.
Is duplication of paired chromosomes in the first stage of meiosis?
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
When do chromosomes replicate?
Chromosomes replicate in the first stage of mitosis or meiosis-interphase
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
What stage occurs when crossing over occurs in meiosis?
Prophase I of Meiosis.
WHEN DO Chromosomes decondense into diffuse chromatin?
At the beginning of Prophase 1 during meiosis. It occurs in a sub-stage of Prophase 1 called Leptonema.
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
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.
During which phase does the chromatin condense into chromosomes?
The chromosomes coil up and condense during prophase
Meiosis leads to variation in offspring by what?
In prophase of meiosis, first, a stage comes (known as crossing over) in which homologous chromosomes, after pairing, exchagne their genetic material. This is the stage where varition occurs during, and only in, meiosis I.
What is the first stage of meiosis?
prophase
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.
