DNA replication results in two identical copies of each chromosome. There needs to be two copies of each chromosome so that at the end of mitosis each daughter cell has the exact same number and types of chromosomes as the original cell. In other words, the daughter cells must have the exact same DNA as the original cell so that each cell has the instructions for carrying out cellular functions.
What else can I help you with?
When does DNA copy itself in mitosis?
DNA copies itself during the S phase of the cell cycle, which occurs before mitosis.
Circle the letter of each sentence that is true about mitosis?
Mitosis occurs in somatic cells Mitosis occurs in gametes Mitosis results in two daughter cells Mitosis results in genetically identical daughter cells True statements: Mitosis occurs in somatic cells Mitosis results in two daughter cells Mitosis results in genetically identical daughter cells
What ensures that each new eukaryotic cell receives a copy of each chromosome?
Mitosis results in two identical cells being produced from the original cell. A copy of each chromosome is made before the cell divides and one of each chromosome goes to each new cell.
What do chromosomes do before mitosis?
Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
When does a cell replicates its entire chromosomal DNA only?
A cell replicates its entire chromosomal DNA only during the S phase of the cell cycle, which occurs before cell division. This ensures that each daughter cell receives an identical copy of the genetic material.
When does DNA copy itself in mitosis?
DNA copies itself during the S phase of the cell cycle, which occurs before mitosis.
Does DNA replicate in mitosis?
no DNA replicates before mitosis. It replicates in the S phase of inter phase
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.
Does mitosis ensure that each new eukaryote cell receives a copy of each chromosome?
Yes, it does! This occurs during G2 phase of Mitosis.
Does DNA replication occur before the division of the nucleus in both meiosis and mitosis?
The cell cycle consists of interphase followed by cell division (in this case mitosis). it's true that DNA replication occurs during interphase, however interphase itself has 3 phases: 1. G1(=gap1): when the cell grows and fuctions 2. S (=Synthesis) when DNA replication occurs (as synthesizing anew DNA copy) 3. G2 (gap2): when the cell accumulates nutrients before the division itself.

How does mitosis ensure that a new plant cell is identical to its parents?
Mitosis ensure that a new cell is identical to its parents by their copy of the parent's genome in mitosis. Identical genetic information will result in identical cells.

How does mitosis ensure that a cell is identical to its parent cell?
Mitosis ensure that a new cell is identical to its parents by their copy of the parent's genome in mitosis. Identical genetic information will result in identical cells.
What makes copies of themselves before mitosis?
The chromosomes are copied, so that each daughter cell has an exact copy of the genetic material.
When does a cell replicates its entire chromosomal DNA only?
A cell replicates its entire chromosomal DNA only during the S phase of the cell cycle, which occurs before cell division. This ensures that each daughter cell receives an identical copy of the genetic material.
