What is the shortest phase of mitosis and why?
The shortest phase of mitosis is anaphase, which comes after metaphase. In this phase, the sister chromatids separate and move towards opposite poles. It is followed by telophase.
Is anaphase the shortest phase of meiosis?
Hint: The shortest phase is a part of Meiosis I in cell division. It involves the separation of homologous chromosomes, which start moving towards the opposite poles after they are aligned at the equator. Complete answer: The shortest phase of mitosis is Anaphase I.
What is the shortest stage of cell cycle?
The shortest stage of the cell cycle is called cytokinesis (division of the cytoplasm). In cytokinesis, the cytoplasm and its organelles divide into two daughter cells. contains a nucleus with an identical set of chromosomes.
What phase of mitosis is the fastest?
When Mitosis Occurs Most Rapidly Mitosis occurs whenever more cells are needed. It happens throughout the entire lifespan of a living organism (human, animal or plant) but most rapidly during periods of growth. This means, in humans, the fastest rate of mitosis happens in the zygote, embryo and infant stage.
What is the shortest and longest phase of mitosis?
Prophase has longest duration, while anaphase has the shortest duration.
What is anaphase short?
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. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes.
Why is the telophase the shortest phase?
During this stage, the cell’s centromeres divide, and each pair of chromosomes is pulled apart. These separated sister chromatids are referred to as daughter chromosomes. Now the cell is ready to enter telophase. This is the shortest and final phase of mitosis.
Why is cytokinesis the shortest phase?
The shortest phase of the cell cycle is cytokinesis because all the previous stages help prepare the cell to divide, so all the cell has to do is divide and nothing else. Chromosomes are pulled to opposite ends of the cell. Chromosomes wind up tightly.
What is the longest stage of the cell cycle called?
G1 is typically the longest phase of the cell cycle. This can be explained by the fact that G1 follows cell division in mitosis; G1 represents the first chance for new cells have to grow. Cells usually remain in G1 for about 10 hours of the 24 total hours of the cell cycle.
Is anaphase the shortest phase of mitosis?
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form.
Why is anaphase so important to cell division?
Anaphase is a stage in mitosis and meiosis where chromosomes begin moving to opposite ends (poles) of a dividing cell . In the cell cycle, a cell prepares for growth and division by increasing in size, producing more organelles and synthesizing DNA .
Why is telophase know as reverse of prophase?
telophase is known as reverse of prophase because in prophase condensation of chromosomes takes place and the nucleolus,endoplasmic reticulum,and the nuclear envelope disappear whereas in telophase alll the disappeared elements of the cell reapper. in telophase chromosomes are uncoiled, and in prophase chromosomes are fully condensed.
Why is interphase the longest phase in the cell cycle?
Interphase is the longest phase because of DNA duplications, replication, chromosomes division take place, so it takes more time for the cell cycle.
Why is prophase the longest stage in the mitosis?
LONGEST PHASE OF MITOSIS. Metaphase is the longest phase of mitosis; in which separation of chromosomes begin by high tension of spindle fibres . At the end of prophase, chromosomes become visible, duplicated centriole forms spindle outside the nucleus and nuclear membrane disappears.
