Note: The shortest phase of the cell cycle is the Mitotic phase (M phase) and the longest phase of the cell cycle is G-1 phase.
Which is the longest phase in Karyokinesis?
A) Karyokinesis I: It is the division of nucleus that takes place in the following stages. i) Prophase I: It is the longest phase of meiosis. It has 5 sub stages. and become short and thick.
Why is anaphase shortest stage in the cell cycle?
Anaphase is considered the shortest stage of the cell cycle because this stage involves only the separation of sister chromatids and their migration.
What is the longest phase in mitosis?
The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope (the membrane surrounding the nucleus) breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell.
Is G1 the longest phase?
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.
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.
What happens in G1 and G2 phase of cell cycle?
Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
Is metaphase the shortest stage of mitosis?
The shortest stage of mitosis is anaphase. Anaphase is the third stage of mitosis, between metaphase and telophase, that only lasts for a few minutes.
Which phase is the shortest phase?
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 metaphase?
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.
What is the longest phase of the cell cycle?
During interphase, the cell undergoes normal growth processes while also preparing for cell division. It is the longest phase of the cell cycle, cell spends approximately 90% of its time in this phase. In order for a cell to move from interphase into the mitotic phase, many internal and external conditions must be met.
Which is the longest and shortest phase of mitosis?
But given the number of events taking place, and the time taken to prepare a cell for its division during Prophase is the maximum compared to all the other phases. It is also a point to be noted, that Anaphase is the shortest stage in Mitosis.
How long is the metaphase?
From the frequency of mitotic phases, defined as indicated in the preceding article (El-Alfy & Leblond, 1987) and corrected for the probability of their occurrence, it was estimated that prophase lasted 4.8 hr; metaphase, 0.2 hr; anaphase, 0.06 hr and telophase, 3.3 hr, while the interphase lasted 5.4 hr.
What is the shortest phase in interphase?
G2 phase is the third, final, and usually the shortest subphase during interphase within the cell cycle in which the cell undergoes a period of rapid growth to prepare for mitosis.
Is s the shortest part of the cell cycle?
The shortest part of the cell cycle is mitosis.
Which is the shortest part of the cell cycle G1 S G2 or mitotic phase?
usually the shortest part of the cell cycle. accounts for about 90% of the cycle. cell grows and copies its chromosomes in preparation for cell division.
Which phase comes between G1 and G2?
Complete answer: Sl.No S phase 1. S phase or synthesis phase is the second sub-phase of interphase. 2. It occurs in between the G1 (Gap 1) phase and G2 (Gap 2) phase. 3. It is the phase of the cell cycle in which DNA replication takes place.
What is the shortest phase of the cell cycle quizlet?
There are three phases of interphase: the S phase and two gap phases. There are two stages to the cell cycle: M phase and interphase. Interphase is typically the shortest of the two stages of the cell cycle. The M phase consists of two events: mitosis and cytokinesis.
Which is the shortest phase of Karyokinesis?
What is the shortest phase of Karyokinesis? Prophase is the shortest phase where condensation of the chromosomes takes place.
Why is telophase the shortest stage?
Each half of the chromosome moves away from its previously adjoining half as the spindle fibers pull them towards opposite ends of the cell. 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.
What are the phase of cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Which is the shortest period in mitosis?
The shortest phase of mitosis is anaphase, which comes after metaphase. In this phase, the sister chromatids separate and move towards opposite poles.
Is G2 the shortest phase in cell cycle?
G2 is the shortest phase of interphase. It is when organelles and proteins necessary for cell division are produced. The cell requires a bunch of proteins and other stuff to separate the chromosomes and divide the cell in half.
