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.
Which is the shortest phase?
M phase is considered as the shortest phase in the cell cycle.
Which of the following phases are longest and shortest in meiosis?
Prophase has longest duration, while anaphase has the shortest duration.
What is the longest phase of meiosis?
Prophase I is the longest and arguably most important segment of meiosis, because recombination occurs during this interval.
Which is the shortest phase of prophase 1?
Leptotene- This is the first stage of prophase I and the shortest phase of prophase I.
- It the phase of a replicated chromosome condensation.
- The chromosomes condense and become compact and visible hence making it possible to distinguish between sister chromatids.
What is the shortest phase of 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.
What is the longest and shortest phase of the cell cycle?
Interphase is usually longest, followed by prophase and telophase; metaphase/anaphase is usually shortest. See p.
Which is the shortest phase of all mitotic phases?
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.
Which is the shortest stage 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.
Which of the following phases are longest and shortest in a?
Explanation: It’s clearly mentioned in the NCERT that, Prophase is longest phase of mitosis. If we want to check whether Anaphase is shortest or not, then as it’s next to Metaphase, during metaphase chromosomes align themselves in single line. And in Anaphase, the only work is movement of chromosomes to the pole.
Why is anaphase the shortest phase of mitosis?
Why is anaphase the shortest stage? The kinetochore microtubules shorten as the chromatids are pulled toward opposite poles, while the polar microtubules subsequently elongate to assist in the separation. Anaphase typically is a rapid process that lasts only a few minutes, making it the shortest stage in mitosis.
What cell phase takes the longest?
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.
What is the longest stage of mitosis Why?
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.
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.
Which is the longest phase of prophase 1?
Diplotene phase is the longest phase of prophase I of meiosis I in oocytes only and can last for months or years.
Why is interphase the longest phase?
The synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration.
