What is happening to the genetic material jsut before a cell leaves interphase and starts prophase of cell division?
As we all know, DNA from a single cell can be more than 4cms long. This long thread is compactly winded to fit it inside a tiny nucleus.
Eukaryotic cells have the DNA winded compactly with the help of special proteins called histones. DNA is wound around the histone proteins to form structures called nucleosomes. Thus, with this "beads-on-string" structure, the overall length is reduced to a considerable extent. Furthermore, these strings now coil upon themselves to develop supercoils which inturn create compact chromosomes. All in all, the total length of the DNA is reduced to such a great extent that a long strand now fits inside a nucleus which is only a few nanometers in diameter (one nanometer = 109 meter).
you can understand the concept further by reading more about
- histones
- nucleosomes
- DNA supercoiling. Wikipedia has wonderful explanations on these topics.
What else can I help you with?
Between anaphase interphase metaphase and prophase which does not belong?
Interphase does not belong because it is not a phase of mitosis. The other three - anaphase, metaphase, and prophase - are stages of mitosis where the cell undergoes specific changes in preparation for division. Interphase is the phase where the cell carries out normal functions and prepares for division.
What is an easy way to explain prophase?
Prophase is the first stage of any cell division (excluding interphase). This is the stage where a cell prepares it for upcoming cell division. Further properties can be found in books and elsewhere.
Does meiosis go through interphase more than once?
No, meiosis only goes through interphase once, before entering the first meiotic division (meiosis I). Interphase consists of G1, S, and G2 phases where DNA is replicated and cells prepare for division.
What are the phases in Mitosis and Meiosis?
In mitosis, the phases are prophase, metaphase, anaphase, and telophase. In meiosis, the phases are similar but with two rounds of division: prophase I, metaphase I, anaphase I, telophase I, followed by prophase II, metaphase II, anaphase II, and telophase II.
What are the six steps in the cell cycle?
The steps are, in this order:Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.Just remember:-Interphase the cell grows, and doubles their DNA in interphase-Mitosis (Just remember the name "In puntacana my apple tastes citrous" - Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokenisis.)-Cytokinesis
What is happening to the genetic material just before a cell leaves interphase and starts prophase of cell division?
replicating
What is the outcome of interphase?
Interphase is where the cell is when it is preparing for cell division. Therefore the purpose of interphase is to prepare the cell for division. During interphase, the cell goes through three stages; the G1, S Phase and G2. This is the longest part of the cycle.
Between anaphase interphase metaphase and prophase which does not belong?
Interphase does not belong because it is not a phase of mitosis. The other three - anaphase, metaphase, and prophase - are stages of mitosis where the cell undergoes specific changes in preparation for division. Interphase is the phase where the cell carries out normal functions and prepares for division.
Each stage of cell division in order?

What is an easy way to explain prophase?
Prophase is the first stage of any cell division (excluding interphase). This is the stage where a cell prepares it for upcoming cell division. Further properties can be found in books and elsewhere.
Does cytokinesis happen during interphase?
No, cytokinesis is the last step of cytokinesis. The steps of cell division are interphase, prophase, metaphase, anaphase, telophase, and cytokinesis.
Does meiosis go through interphase more than once?
No, meiosis only goes through interphase once, before entering the first meiotic division (meiosis I). Interphase consists of G1, S, and G2 phases where DNA is replicated and cells prepare for division.
Which two phases are the nuclear membranes present?
The nuclear membranes are present during the interphase and the prophase of mitosis. During interphase, the nuclear envelope surrounds the nucleus, protecting the genetic material. In prophase, the nuclear membrane begins to break down as the cell prepares for division. After this phase, the nuclear envelope re-forms during telophase.
What are the phases in Mitosis and Meiosis?
In mitosis, the phases are prophase, metaphase, anaphase, and telophase. In meiosis, the phases are similar but with two rounds of division: prophase I, metaphase I, anaphase I, telophase I, followed by prophase II, metaphase II, anaphase II, and telophase II.
What HAPPENS DUR?
Mitosis is the division of the chromosomes in the nuclei. There are 5 stages in mitosis. Interphase, prophase, metaphase, anaphase, and telophase.

What happens durring mitosis?
Mitosis is the division of the chromosomes in the nuclei. There are 5 stages in mitosis. Interphase, prophase, metaphase, anaphase, and telophase.
