If you are referring to prophase of mitosis, the cell's chromatin is condensing into organized chromosomes, visible under the light microscope. Spindle fibers are attaching to the centromeres and the centrioles are moving to the poles of the cell.
The two phases of prophase during meiosis are different though.
Prophase is a step in the process of cell division in animals, called mitosis. During prophase, the chromatin fibers present in the nucleus coil tightly into observable chromosomes. The mitotic spindle begins to form; the centrosomes move away from each other and spindle microtubules begin to grow from them.
this phase begins with condensation of chromosomes along their length.
at the end of the each chromosomes to be made up of two chromatids and a centromere holding them together.after the chromosomes migrate towards nuclear membrane away from the center of nucleus
Pro-phase is characterized by-
1. Nucleus appears large.
2. Chromatin material is clearly visible.
3. Chromatin material start to condense.
4. Nucleolus is prominent.
Primero debes tener en cuenta en que sytema esta consituido. 1.la telophase nunca interviene con el nucleo.
2. la telophase simple esta unida con el ADN.
Chromosomes are aligned at the equator.
Spindle fibres are attached to the centromere.
it moves around
waht changes in the chromosomes occur during meiosis
Chromatin changes to thick rods called chromosomes during anaphase. During anaphase the centromeres divide and are pulled apart by the spindle fibers. They then move to opposite ends of the poles.
yes, during prophase
There is still only 1 cell during prophase.
prophase consist of G1, S, G2 phase during which DNA replicates (it is copied) and cell grows (to double size)
waht changes in the chromosomes occur during meiosis
During mitosis, chromosomes are in their most condensed form during metaphase
Chromatin changes to thick rods called chromosomes during anaphase. During anaphase the centromeres divide and are pulled apart by the spindle fibers. They then move to opposite ends of the poles.
Chromosomes form during Prophase of Mitosis.
The chromosomes coil up and condense during prophase
Crossing over occurs during Prophase I of meiosis.
yes, during prophase
Tetrads line up in the middle of the cell during metaphase I.
There is still only 1 cell during prophase.
prophase consist of G1, S, G2 phase during which DNA replicates (it is copied) and cell grows (to double size)
prophase I
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.
