What else can I help you with?
When choromosomes are visible in the nucleus?
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
What do you call the separation of the nucleus in cell division?
The separation of the nucleus during cell division is called mitosis in somatic cells and meiosis in reproductive cells. During mitosis, the nucleus divides into two identical nuclei, while meiosis results in four genetically diverse nuclei. Both processes are crucial for growth, development, and reproduction in living organisms.
In Mitosis What organelle does the division of the nucleus?
In mitosis, the division of the nucleus is carried out by the spindle fibers. These fibers are formed by the microtubules and are responsible for separating the duplicated chromosomes into two sets in the process called cytokinesis.
Which meiosis better mirrors the mitosis process?
Meiosis I better mirrors the mitosis process because during this stage the homologous chromosomes separate, similar to the way sister chromatids separate during mitosis. Meiosis II, on the other hand, involves separating sister chromatids, which is not seen in mitosis.
What happens in karyokinesis and cytokinesis?
Karyokinesis is the phase during mitosis during which the nucleus of a diploid cell splits to form two separate nuclei in whats known as a "clevage" from the anaphase to the telophase during mitosis. And is only obtained due to the pull of the protein fibres or spindles by the centrioles.
When choromosomes are visible in the nucleus?
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
The nucleus and nucleolus disappear during what?
The nucleus and nucleolus disappear during cell division, specifically during the prophase stage of mitosis. This is when the nuclear envelope breaks down, allowing the chromosomes to condense and become visible. The nucleolus also disappears as the cell prepares to divide into two daughter cells.
The nucleus is divided during?
The nucleus divides during cell division, specifically during the process of mitosis in somatic cells and meiosis in sex cells. Mitosis results in two identical daughter cells with the same number of chromosomes as the parent cell, while meiosis creates gametes with half the number of chromosomes to ensure genetic diversity.
What are structures inside the nucleus that duplicate when a cell undergoes mitosis and separate when a cell undergoes meiosis?
Chromosomes are the structures inside the nucleus that duplicate during mitosis and separate during meiosis. Each chromosome consists of two identical sister chromatids held together by a centromere. During cell division, these sister chromatids are separated to ensure each daughter cell receives the correct number of chromosomes.
What is a period of nuclear division in a cell called?
The division of nucleus and its parts during cell division is called Cytokinesis.Firstly, during Prophase the nucleus membrane starts disappearing and then after(Metaphase,Anaphase)it, in Telophase it again appears when the daughter cells are almost forming. Here the division of nucleus ends an then the division of cytoplasm takes place which is called Karyokinesis.
What is the function chromosomes?
To preserve the DNA for replications during mitosis and meiosis.
In Mitosis What organelle does the division of the nucleus?
In mitosis, the division of the nucleus is carried out by the spindle fibers. These fibers are formed by the microtubules and are responsible for separating the duplicated chromosomes into two sets in the process called cytokinesis.
What phase of mitosis spindle fibers disappear and new nucleus form at each end?
The phase of mitosis that the nucleus forms is the prophase phase.
Is DNA replicated during mitosis or meiosis?
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
How is the chromosome number halved during cell division: mitosis or meiosis?
The chromosome number is halved during cell division in meiosis, not mitosis.
The division of the cell nucleus called?
The division of the cell nucleus is called mitosis. During mitosis, the cell's chromosomes are replicated and divided equally into two daughter cells. This process ensures that each new cell receives a complete set of genetic information.
Which meiosis better mirrors the mitosis process?
Meiosis I better mirrors the mitosis process because during this stage the homologous chromosomes separate, similar to the way sister chromatids separate during mitosis. Meiosis II, on the other hand, involves separating sister chromatids, which is not seen in mitosis.
