Why are the chromosomes not condensed during all stages of mitosis?

When replicating or during transcription, DNA needs to uncoil in order to give the proper code. When the chromosomes are condensed, it cannot uncoil itself to give any sort of message. In order for the cell to remain functional, it must be able to code DNA.

∙ 9y agoDuring transcription, as well as during the replication during cell division, the DNA needs to uncoil so that the DNA can be properly used. As such, if the chromosomes stayed condensed the whole time, these processes couldn't occur.

∙ 12y agoThe chromosomes aren't condensed, only the chromatin and the nucleus. The chromosomes lose their rodlike appearance in Telophase. That's when th chromosomes starts turning into chromatin, which is right after the nuclear envolope starts to form around the chromosomes.

Wiki User
∙ 11y agoBecause they are most condensed during mitosis.

∙ 14y agoBecause the chromosomes are uncoiled.

How many chromosomes will the resulting cells have in mitosis?
This depends both on the cell undergoing mitosis and the stage in mitosis which is currently underway. Humans have 46 chromosomes per cell, but in some stages of mitosis have 92. Dogs have 78 chromosomes, but at some stages of mitosis have 156.
In what stages of the reproductive process does meiosis occur?
in the production of eggs and of sperm the mitosis stage before the chromosomes are copied
In which of the stages does each chromosome consist of two DNA molecules?
(From the end of the S phase of interphase through the metaphase of mitosis). In eukaryotes, throughout the entire life of the Cell, also called the cell cycle. During Mitosis the chromosomes are separated.
What happens during prophase you that does not happen during mitosis?
Prophase is one of the stages in the process of mitosis, the stages of mistosis are : 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase. So metaphase, anaphase, and telophase are what happends in mitosis and does not happen in prophase. And what happens in prophase that does not in mitosis is that the sister chromatids that were formed during interphase have shortened and thickened and are now visible with a light microscope.
Strictly speaking mitosis and meiosis are divisions of the?
Mitosis is division of a cell. Consists of the stages Prophase, Metaphase, Anaphase, and Telaphase. Mitosis is part of the cell cycle. Meiosis is the division of a sex cell. Such as sperm or egg. Meiosis is unique because it goes through the stages twice. Prophase I, Prophase II, Metaphase I, and Metaphase II, etc.
During which phase of mitosis are chromosomes attaching to the spindle?
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
What is the role of the spindle during mitosis?
It provides a "scaffolding" for the attachment and movements of the chromosomes during the later mitotic stages.
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.
What stages of mitosis are chromosomes single structures composed of one chromatin?
Anaphase
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.
How many chromosomes will the resulting cells have in mitosis?
This depends both on the cell undergoing mitosis and the stage in mitosis which is currently underway. Humans have 46 chromosomes per cell, but in some stages of mitosis have 92. Dogs have 78 chromosomes, but at some stages of mitosis have 156.
Each phase of mitosis?
The four stages of Mitosis is: Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. Metaphase:the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle fibers Anaphase:The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle fiber. Telophase: The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
If a a cell has 2 cells is it mitosis?
No, but you are close. Mitosis is also called cell division. Do not mix it up with meiosis. There are 4 stages of mitosis: Prophase, Metaphase, Anaphase, and Telephase. During mitosis, chromosomes form, line up in the center of the cell, get surrounded by the spindles of the centrioles, and finally split in two.
How is a chromosome different from chromatin and how are they similar?
Chromosomes exist [in interphase] as de-condensed, or free, potential chromatin; while chromatin is chromosomes that are condensed [wound] around histone proteins. This condensation, or packing, of the chromosomes occurs in two stages: first the Dna strand is wound around Histone proteins that then spiral into The Ten Nanometer Fiber. This spiraled compact 10 nm fiber is then further wound up into the Thirty Nanometer Fiber, the chromatin, which is then further folded [condensed] into The Chromosomes.
What stages of the cell cycle include anaphase cytoplasmic division mitosis interphase g1 stage g2 stage?
Anaphase is the stage of mitosis when chromosomes separate.
What all the different stages of mitosis?
Define Mitosis: the equal division of the chromosomes into two genetically identical daughter nuclei.Mitosis consist of four stages:Prophase- chromosomes form from condensed chromatin.Metaphase- the chromosomes line up along the center axis of the cell.Anaphase- the chromosomes split up and chromatids are pulled to opposite ends of the cell.Telophase- a new nuclear membrane forms around each set of chromatids.To remember the stages of Mitosis in order think of this: You have a large, long "mat" in front of you with a big bold letter "P" on it.
In what stages of the reproductive process does meiosis occur?
in the production of eggs and of sperm the mitosis stage before the chromosomes are copied
