Mitosis is the process of cell division in which the chromosomes condense and the spindle is assembled. In each phase the chromosomes do different things: prophase: during this first phase of mitosis, the parent chromosomes become compacted and the spindle begins to form creating an X-shape when looked at through a microscope; prometaphase: the nuclear membrane becomes many small vesicles during this phase. The spindle microtubules reach out until they connect the chromosomes to their kinetochore and then a sort of "tug-of-war" happens while the chromosomes bounce between the two poles; metaphase: the chromosomes align along the equator of the cell as they become connected to the spindle poles; anaphase: the chromosomes work their way into becoming individual/independent chromosomes as they begin to find their place near the poles; and telophase: the chromosomes find their poles, the spindle disbands, and each chromosome gets its new nuclear membrane.
What else can I help you with?
What event occurs during metaphase?
The chromosomes attach to a spindle fiber across the equator of the cell.
What happens if germs get near you?
Nothing. Germs have to be bad germs and have to get into you to harm you.
What happens if you put algae near sunlight?
Yes the sun is where algae gets its energy.
What is the process by which sediment in water settles in new locations?
it makes a new land near water like the sea
What months do the sun strike the equator directly?
That happens at some point on the equator, at a single moment, on two days of the year ... near March 21 and near September 21.
What happens to the chromosomes near the end of mitosis?
two new nuclei form around them.... if u didnt know that finish school
What part of a cell assist in the cell division process?
The process is called Mitosis. Some parts are:centriolesspindle fiberschromosomesDNAmicrotubulescentromeres
What event occurs during metaphase?
The chromosomes attach to a spindle fiber across the equator of the cell.
Once chromosomes have copied during interphase the cell is ready to begin what process?
Near the end of interphase, the chromosomes double. Now the process of mitosis can begin. The phases, in order, that follow are prophase, metaphase, anaphase, telophase, and cytokinesis. During cytokinesis, the cytoplasm divides and the resulting daughter cells each return to interphase where they spend most of their existence carrying out life processes. At some later point, the cell membrane is unable to handle the flow of materials into and out of the cell. The chromosomes double and mitosis occurs again.
What is the area near the nucleus that is made of two centrioles?
The area near the nucleus that is made of two centrioles is the centrosome. Centrioles play a key role in cell division by organizing the spindle fibers that separate the chromosomes during mitosis.
Where do you find the centrioles aid in cell division?
It helps divide DNA during cell division!! :) <3
The part near the nucleus that helps with reproduction?
The organelle near the nucleus that helps with reproduction is the centriole. Centrioles play a key role in cell division by organizing the mitotic spindle, which is crucial for separating chromosomes during cell division.
What involved in cell division in animal cells?
Centriole
Why chromosome observed in prophase but not in interphase?
Chromosomes are condensed and visible in prophase due to the coiling of DNA to form compact structures. In interphase, chromosomes are in their less condensed state, called chromatin, making them less visible under a microscope. This allows for gene expression and DNA replication to occur before cells enter mitosis and condense their chromosomes again.
What are the four phases of mitosis.?
The events of mitosis, or the stages, are prophase, metaphase, anaphase and telophase. A way to remember the order of the stages is "PMAT."In prophase, the cell multiplies its genetic materials. In metaphase they line evenly across the center of the cell to prepare to split. In anaphase, the cell begins to separate and the genetic material moves toward the poles. The last stage, telophase, is when the cell has successfully split into two genetically identical cells. This happens in plant cells.The first and longest phase of mitosis, prophase, can take as much as 50-60% of the total time required to complete mitosis. During prophase, the chromosomes become visible. The Centrioles, two tiny structures located in the cytoplasm near the nuclear envelope, separate and take up positions on opposite sides of the nucleus.The Centrioles lie in a region called the centrosome that helps to organize the spindle, a fanlike microtubule structure that helps separate the chromosomes. During prophase, the condensed chromosomes become attached to fibers in the spindle at a point near the Centromere of each Chromatid. Interestingly, plant cells do not have centrosomes, but still organize their mitotic spindles from centrosomes.Near the end of the prophase, the chromosomes coil more tightly. In addition, the nucleolus disappears, and the nuclear envelope breaks down.Prophase: Chromosomes condense, centrioles form, Metaphase chromosomes lineup at the metaphase plate (midline), anaphase chromatids separate and are pulled at centrioles by kinetochores, and teleophase: nucleus reforms, and cytokinesis the cells bud from each other.....
When water evaporates the air near the surface becames cooler explain why this happens?
Evaporation is an endothermic process (absorption of heat).
What organelles are used to move chromosomes?
Chromosomes are moved during cell division by the spindle fibers, which are made up of microtubules originating from the centrosomes. The centrosomes are organelles located near the nucleus in animal cells and help to organize the mitotic spindle during cell division.
