These basic events of mitosis include chromosome condensation, formation of the mitotic spindle, and attachment of chromosomes to the spindle microtubules. Sister chromatids then separate from each other and move to opposite poles of the spindle, followed by the formation of daughter nuclei.
What are the four phases of mitosis what events occur during each phase?
The process in which the nucleus of a eukaryotic cell divides is called mitosis. During mitosis, the two sister chromatids that make up each chromosome separate from each other and move to opposite poles of the cell. Mitosis occurs in four phases. The phases are called prophase, metaphase, anaphase, and telophase.
What are the phases of meiosis What are the major events of each phase?
Major Events in Meiosis
|Anaphase I||Two chromosomes of each with two chromatids of each homologous pair separate and move toward opposite poles.|
|Telophase I||Chromosomes arrives at the spindle poles|
|Cytokinesis||Cytoplasm divides to produce two cells, each having half the original number of chromosomes|
Which of the following is true of mitosis?
The correct answer is A. It maintains the same chromosome number in the daughter cells as in the parent cell. Explanation: Mitosis is also known as equational division because in mitosis the replicated chromosome becomes equally divided and distributed into two daughter cells.
What are the major events of meiosis and when do they occur?
Chromosomes condense, homologous chromosomes synapse, crossing over takes place, nuclear envelope breaks down, and mitotic spindle forms. You just studied 11 terms!
What is the shortest phase of meiosis?
Mitotic phase or the division phase is very short lived. In mitosis, prophase is the longest and anaphase is the shortest. Metaphase and telophase are of nearly same duration.
How long is each phase in mitosis?
The time required then for the complete process of mitotic cell division would lie within the following limits: Prophase, 30 to 60 minutes; metaphase, 2 to 10 minutes; anaphase 2 to 3 minutes; telophase 3 to 12 minutes and the reconstruction period from 30 t’o 120 minutes: total 70 to 180 minutes.
Which is the shortest phase in Karyokinesis?
__________is the shortest phase of karyokinesis ???
- hi mate here is your answer ⏬⏬⏬⏬⏬⏬
- the shortest stage of mitosis in anaphase . anaphase is third stage of mitosis between metaphase and telophase that only last for few minutes.
