Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell.
What phase does chromosomes appear?
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible.
What three phases are individual chromosomes no longer visible?
It is during interphase, telophase, and cytokinesis that the chromosomes are no longer visible.
Why is mitosis important for life?
Importance of Mitosis in Living Process
Genetic stability– Mitosis helps in the splitting of chromosomes during cell division and generates two new daughter cells. … Growth- Mitosis help in increasing the number of cells in a living organism thereby playing a significant role in the growth of a living organism.
What happens to DNA in each stage of mitosis?
This process involves replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm. … The outcome of binary fission is two new cells that are identical to the original cell.
How many chromosomes are visible at the end of meiosis?
Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
How many chromosomes are visible at the beginning of meiosis?
At the beginning of meiosis I, a human cell contains 46 chromosomes, or 92 chromatids (the same number as during mitosis).
