It occurs before mitosis, in the S-phase (synthesis) of interphase.
What else can I help you with?
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.
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.
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.
What is copied before mitosis begins?
DNA, the genetic material, of course. Also mitochondria and chloroplasts need to divide. This is the process of mitosis where two daughter cells are produced and both will need the complete complement of genetic material; DNA.
Does synthesize DNA occur in mitosis?
yes
What is the DNA of mitosis?
There is no DNA of mitosis. Before mitosis, the DNA must be replicated, which occurs during interphase of the cell cycle.
Does DNA replication occur after telophase 1?
Telophase is a phase of mitosis. DNA replication must occur before mitosis begins. If it does not then the DNA chromosomes may not be consistent throughout the division of the cells.
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.
Before mitosis or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
What process must occur before mitosis and meiosis produces two identical dna strands from one original template and uses dna polymerase enzyme to produce the copy?
DNA replication
When does doubling of DNA occur?
The doubling of DNA (known as DNA synthesis or DNA replication) occurs during the "S (synthesis) phase" of the cell cycle. This is part of interphase, and occurs before mitosis (cell division).
What event must occur outside the nucleus before mitosis can begin?
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
