There are four phases that occur in mitosis. The first phase of mitosis is prophase. Cells that are in prophase have an enlarged nucleus and the cell’s chromosomes are in short, jumbled strands.
Which 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.
Is telophase the longest stage of mitosis?
Also, it is divided into an early and late stage. So clearly, the longest phase of the Mitosis is Prophase.
How long does it take to grow the first 20 cells?
Answer: About 2-3 hours .
Why is anaphase so short?
Anaphase is considered the shortest stage of the cell cycle because this stage involves only the separation of sister chromatids and their migration…
How many generations are required to produce 256 cells?
Every mitotic division will lead to the formation of twice the number of mother cells, hence to form 256 cells from a root tip cell, 8 generations of mitotic divisions must occur (28=256 cells).
How quickly do cells multiply?
Most growing plant and animal cells take 10 – 20 hours to double in number, and some duplicate at a much slower rate. Many cells in adult animals, such as nerve cells and striated muscle cells, do not divide at all.
How long does the metaphase stage last?
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.
How many minutes does telophase take?
We find that in a 24-hour period, the cells we observed spend 1000.2 minutes in interphase, 180 minutes in prophase, 128.2 minutes in metaphase, 77.8 minutes in anaphase, and 51.8 minutes in telophase.
