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.
How many cells are in prophase during the process of cell division?
During prophase of cell division, there are typically 46 cells in humans.
In which stage of cell division, mitosis or meiosis, does crossing over occur?
Crossing over occurs during the prophase I stage of meiosis.
Number of cells during prophase?
During prophase of mitosis, the number of cells remains constant. Prophase is the first stage of mitosis where the nucleus condenses and the chromosomes become visible, but the cell itself does not divide yet.
What specific changes in the cell cycle occur during mitosis in a plant cell?
During mitosis in a plant cell, the cell undergoes several specific changes in the cell cycle. These changes include prophase, where the chromosomes condense and the nuclear envelope breaks down; metaphase, where the chromosomes line up at the center of the cell; anaphase, where the sister chromatids separate and move towards opposite poles of the cell; and telophase, where the nuclear envelope reforms and the chromosomes decondense. This process ensures that each daughter cell receives an identical set of chromosomes.
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.
When during the cell cycle are chromosome visible?
During Prophase
In what part of the cell does the replication occur?
DNA replication occurs during Interphase. This is not normally part of the cell division cycle but interphase must occur before subsequent stages such as prophase and metaphase can occur.
How many cells are in prophase during the process of cell division?
During prophase of cell division, there are typically 46 cells in humans.
In Which phase the nucleolus begins to fade from view of the cell cycle?
The nucleolus begins to fade from view during prophase.
In what phase does chromosomes condense and become visible?
The chromosomes in a cell's nucleus are only visible during the part of the cell cycle known as prophase. Prophase is the stage of mitosis in which chromatin condensation occurs.
When does crossing over occure?
prophase I
In which stage of cell division, mitosis or meiosis, does crossing over occur?
Crossing over occurs during the prophase I stage of meiosis.
Can chromosomes be seen in a cell that is observed in prophase?
Yes. During prophase the chromosomes condense to prepare for cell division.
Number of cells during prophase?
During prophase of mitosis, the number of cells remains constant. Prophase is the first stage of mitosis where the nucleus condenses and the chromosomes become visible, but the cell itself does not divide yet.
During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I of meiosis. This is when homologous chromosomes align along the equator of the cell, creating tetrads with pairs of homologous chromosomes.
If a skin cell has 40 micrograms of DNA during G1 how much DNA will it have during prophase?
During prophase, when the cell is preparing for cell division, the amount of DNA in a skin cell remains the same as in G1 phase. So, the skin cell will still have 40 micrograms of DNA during prophase.
