What else can I help you with?
What would happen to the amount of cellular DNA when cells divides if DNA replication did not occur?
If DNA replication did not occur, then when the cell divides the amount of DNA available would be divided. Half going into the knew cell the other half remaining in the parent cell. Each cell would then contain only half the number of chromosomes that it should have and would die fairly quickly.
Explain why DNA replication must occur before mitosis starts?
DNA replication must occur before mitosis starts to ensure that each daughter cell receives a complete and identical copy of the genetic information. If DNA replication did not occur before mitosis, the daughter cells would have only half of the necessary genetic material, leading to genetic abnormalities and potentially cell death.
In what phase of mitosis does DNA replication occur?
DNA replication occurs during the S phase of the cell cycle, which is before mitosis begins.
Before a cell divides the DNA must duplicate itself by what?
Before a cell divides, the DNA must duplicate itself through a process called DNA replication. This process ensures that each new cell receives an identical copy of the genetic information stored in the original cell's DNA.
When a cell divides into two and duplicates its genetic material the process is called?
Mitosis and cytokinesis, although the process is reversed from what you ask in your question. During mitosis a cell duplicates its genetic material and then it divides into two new cells during cytokinesis.
When does replication occur in cell's cycle?
Replication of DNA occurs during Interphase of both mitosis and meiosis. This means the DNA is doubled before the cell divides.
Where does DNA replication form?
DNA replication occurs in the nucleus of the cell - just before the cell divides.
Where does DNA form?
DNA replication occurs in the nucleus of the cell - just before the cell divides.
Why must the DNA In a cell replication before the cell divides?
DNA replication begins when the two sides of the DNA molecule unwind and seperate, like a zipper unzipping.
When does chromosomal replication occur?
Chromosomal replication occurs during the S phase of the cell cycle, which is part of interphase. During this phase, the DNA in a cell is replicated to ensure that each daughter cell will receive a complete set of chromosomes.
Why DNA replication needed a cell divides into two daughter cells?
DNA replication is necessary before cell division to ensure that each daughter cell receives an identical copy of the genetic material. This process is crucial for maintaining genetic information continuity across generations and ensuring proper functioning of the cells. Without accurate DNA replication, errors in genetic information could occur, leading to mutations and potential disruptions in cell function.
In what part of the cell does the replication occur?
DNA replication occurs during Interphase. This is not normally part of the cell division cycle but interphase must occur before subsequent stages such as prophase and metaphase can occur.
DNA replication occurs?
The Replication of DNA does occur before the cell can divide.
What would happen to the amount of cellular DNA when cells divides if DNA replication did not occur?
If DNA replication did not occur, then when the cell divides the amount of DNA available would be divided. Half going into the knew cell the other half remaining in the parent cell. Each cell would then contain only half the number of chromosomes that it should have and would die fairly quickly.
