Explain about prophase ll metaphase ll Anaphase ll and Telophase ll
Answers
Answer:
Prophase ll
Meiosis II is initiated immediately after cytokinesis usually before the chromosomes have fully elongated. In contrast to meiosis I, meiosis lI resembles a normal mitosis. The nuclear membrane disappears by the end of prophase lI. The chromosomes again become compact.
Metaphase ll
At this stage the chromosomes align at the equator and the microtubules from opposite poles of the spindle get attached to the kinetochores of sister chromatids.
Anaphase ll:
It begins with the simultaneous splitting of the centromere of each chromosome allowing them to move toward opposite poles of the cells by shortening of microtubules attached to kinetochores.
Telophase ll:
Meiosis ends with telophase Il, in which the two groups of chromosomes once again get enclosed by a nuclear envelope;cytokinesis follows resulting in the formation of tetrad of cells i.e., four haploid daughter cells.
Answer:
MetaphaseII
Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. ... There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.
AnaphaseII
Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. ... The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
TelophaseII
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. ... During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm.
