Give example of mitosis cell division?
Both Mitosis and Mitosis are mechanisms that describe cell division. The difference is particularly noticeable when one looks at the DNA in the cell's nucleus. After mitosis, each of the daughter cells will have exactly the same DNA strands, while after meiosis each daughter cell will only have half of the DNA strands, sometime the division is not exactly half and half, but that is not really on the right subject. Because meiosis only has half the information that the parent cell had, the call is unable to reproduce by itself. The reason for meiosis is for reproduction of a multi-cellular organism. One daughter cell, from the male of the sides, will try to find a compatible daughter cell, from the female side, and fertilize it. This then becomes an embryo and the specie has succesessfully reproduced.
Why must chromosomes be duplicated before mitosis?
Chromosomes must be duplicated before mitosis to ensure that each daughter cell receives an exact copy of the genetic material present in the parent cell. This duplication allows for the accurate distribution of genetic information to maintain genetic stability and facilitate proper cell division.
Why does DNA make an exact copy of itself?
DNA is often called the blue print of an individual's life. It has the make-up of what every trait and characteristic inside and outside of the body will be. It is important for DNA to replicate itself in order to reproduce. Everyone has genes that were passed down from their parents. Each parent gives exactly one copy of their genes to each child they have. Every new cell needs a copy of DNA, so it is the DNA's job to replicate itself and pass on a copy to an organism.
In what type of cell does mitosis occur?
Mitosis occurs in eukaryotic cells, which are cells with a defined nucleus and membrane-bound organelles. Most multicellular organisms go through mitosis during growth, repair, and asexual reproduction.
Is interphase considered as resting stage?
No, interphase is not considered a resting stage. It is a phase in the cell cycle where the cell prepares for cell division by growing, replicating its DNA, and carrying out normal cellular functions. The cell is actively synthesizing proteins and preparing for mitosis.
When does DNA replicate during mitosis?
DNA replicates during the S phase of the cell cycle, which occurs before mitosis.
When do chromosomes (DNA) replicate?
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
Before a cell can go through mitosis the DNA must replicate during intephase?
Replication
Why does the cell need to replicate its DNA for mitosis?
The cell needs to replicate its DNA for mitosis to ensure that each daughter cell receives a complete set of genetic information. Replicating the DNA ensures that each daughter cell will have all the necessary genetic material to perform its functions and carry out cellular processes.
What is the longest part of mitosis?
There are five stages of mitosis, beginning with interphase and ending with telophase. Interphase is the longest phase, during which the centrioles and DNA replicate and preparations are made for mitosis to occur.
During what part of the mitosis does the DNA replicate?
The DNA replicates during the S phase of the cell cycle, which occurs before mitosis starts. DNA replication ensures that each daughter cell receives a complete set of genetic information during cell division.
During what part of the mitosis process dose the DNA replicate?
DNA replicates during the S phase of interphase, which occurs before mitosis. In the S phase, each chromosome is replicated to form two identical sister chromatids connected at the centromere.
How does the cell replicate DNA?
Cells do not replicate "In DNA". Cells replicate their DNA during the process of cell division.
What happens to DNA before cell division in mitosis?
No, transcription is the process of creating an mRNA copy of the DNA in order to create a function process (by translation at the ribosomes). However, DNA does replicate before mitosis occurs - this is so that each daughter cell at the end of mitosis ends up with the same number of chromosomes as the original cell.
How do cells Replicate?
Cell replication, also known as cell division, involves a series of intricate steps. First, the cell's DNA is copied during the S phase of the cell cycle. Then, the cell's nucleus divides through mitosis, ensuring each daughter cell receives a complete set of genetic information. Finally, the cytoplasm divides during cytokinesis, producing two separate daughter cells that are genetically identical to the parent cell.
What must occur with the DNA in the original cells in order for mitosis to make new cells?
DNA replication must occur in the original cells before mitosis can take place. This ensures that each new cell receives a complete set of genetic information. During mitosis, the replicated DNA is separated and distributed to the new daughter cells.
What are chromosomeswhere and when they are visible in the cell?
Chromosomes contain tightly-packed DNA, and are visible only when the cell is preparing to replicate (before mitosis/meiosis).
