What else can I help you with?
What is duplicated during the process of mitosis?
DNA duplication occurs during the interphase, specifically the S phase. After replication, the cell then enters the first active phase of mitosis.
Chromosomes form during what?
Chromosomes form during cell division, specifically during the process of mitosis. During mitosis, the chromosomes condense and line up before being separated into two daughter cells.
Are chromosomes equally distributed in mitosis or interphase?
Chromosomes are equally distributed during mitosis, specifically during the metaphase and anaphase stages, when sister chromatids are separated and pulled to opposite poles of the cell. In contrast, during interphase, chromosomes are not evenly distributed, as they exist in a less condensed form called chromatin and are replicated in preparation for cell division. Thus, the equal distribution of chromosomes occurs specifically during mitosis, not interphase.
Is mitosis same as karyokinesis?
No, mitosis refers to the division of the cell's nucleus, while karyokinesis specifically refers to the division of the nucleus during cell division. Karyokinesis is a part of mitosis, along with cytokinesis which involves the division of the cytoplasm.
What cellular parts disappear and what parts reappear at this stage of mitosis?
During the prophase stage of mitosis, the nuclear envelope disappears, and the nucleolus fades from view. The chromatin condenses into visible chromosomes, which consist of two sister chromatids joined at the centromere. As mitosis progresses into metaphase, the spindle fibers emerge, attaching to the centromeres of the chromosomes. The nuclear envelope will reappear in the later stages of mitosis, specifically during telophase.
Use of acetocarmine in onion root tip squash?
Acetocarmine is a DNA specific stain like feulgen stain, so the super coiled chromosomes during different stages of mitosis present in the Onion root tip cells can be visualized perfectly by treating with this stain.
What is duplicated during the process of mitosis?
DNA duplication occurs during the interphase, specifically the S phase. After replication, the cell then enters the first active phase of mitosis.
Chromosomes form during what?
Chromosomes form during cell division, specifically during the process of mitosis. During mitosis, the chromosomes condense and line up before being separated into two daughter cells.
Does crossing over occur during mitosis?
No, crossing over does not occur during mitosis. Crossing over is a genetic process that happens during meiosis, specifically during prophase I, where homologous chromosomes exchange genetic material. Mitosis is a different type of cell division that does not involve crossing over.
Are chromosomes duplicated during interphase or mitosis?
Chromosomes are duplicated during interphase, specifically during the S phase of the cell cycle. Mitosis is the process of cell division where the duplicated chromosomes are separated into two daughter cells.
Are chromosomes equally distributed in mitosis or interphase?
Chromosomes are equally distributed during mitosis, specifically during the metaphase and anaphase stages, when sister chromatids are separated and pulled to opposite poles of the cell. In contrast, during interphase, chromosomes are not evenly distributed, as they exist in a less condensed form called chromatin and are replicated in preparation for cell division. Thus, the equal distribution of chromosomes occurs specifically during mitosis, not interphase.
Why use acetocarmine stain?
we use acetocarmine to stain chtomosomes. stained chromosomes distinguish from the other organels and materials, it gives the chromosomes a red color. it enables that, during the cell cyle we can observe the nucleus, duplication of DNA, and movement.
Can crossing over occur during mitosis?
No, crossing over does not occur during mitosis. It is a process that happens during meiosis, specifically during prophase I. During crossing over, genetic material is exchanged between homologous chromosomes, leading to genetic variation in offspring.
Is mitosis same as karyokinesis?
No, mitosis refers to the division of the cell's nucleus, while karyokinesis specifically refers to the division of the nucleus during cell division. Karyokinesis is a part of mitosis, along with cytokinesis which involves the division of the cytoplasm.
During what part of the mitosis process does dna replicate?
During interphase (more specifically the S-stage), the chromosomes are duplicated.
Do crossovers usually occur during mitosis?
No, crossovers do not occur during mitosis. Crossovers, also known as genetic recombination, happen during meiosis, specifically during prophase I. Mitosis is the cell division process that results in two identical daughter cells, while meiosis is the cell division process that results in four genetically unique daughter cells.
When do nuclear membranes start to form during cell division?
Nuclear membranes start to form during cell division in the late stages of mitosis, specifically during telophase.
