During mitosis, DNA is replicated by the process of DNA synthesis, where the DNA molecule unwinds and separates into two strands. Each strand serves as a template for the creation of a new complementary strand, resulting in two identical copies of the original DNA molecule. This ensures that each daughter cell receives a complete set of genetic information during cell division.
What else can I help you with?
Is DNA replicated during mitosis or meiosis?
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
Which phase is the DNA replicated in during mitosis?
Chromatin (DNA in loose form) is replicated in the S phase of interphase. Interphase follows prophase and is comprised of a G1 phase, S phase, and G2 phase.
Why is DNA replicated during interphase before mitosis?
DNA is replicated during interphase before mitosis to ensure that each new cell receives a complete set of genetic information. This process helps maintain genetic stability and allows for accurate 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 are chromosomes replicated during mitosis?
During mitosis, chromosomes are replicated through a process called DNA replication. This involves the unwinding of the DNA double helix, the separation of the two strands, and the synthesis of new complementary strands. This results in two identical copies of each chromosome, which are then separated into two daughter cells during cell division.
Is DNA replicated during mitosis or meiosis?
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
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.
What is duplicated during the process of mitosis?
DNA duplication occurs during the interphase, specifically the S phase. After replication, the cell then enters the first active phase of mitosis.
When does a cell's DNA get replicated?
During S phase Right before mitosis begins
Which phase is the DNA replicated in during mitosis?
Chromatin (DNA in loose form) is replicated in the S phase of interphase. Interphase follows prophase and is comprised of a G1 phase, S phase, and G2 phase.
Why is DNA replicated during interphase before mitosis?
DNA is replicated during interphase before mitosis to ensure that each new cell receives a complete set of genetic information. This process helps maintain genetic stability and allows for accurate cell division.
When does replication happen during mitosis or meiosis?
Replication occurs during the S phase of the cell cycle before both mitosis and meiosis. In mitosis, the replicated DNA is separated into two identical daughter cells. In meiosis, the replicated DNA is separated into four haploid daughter cells with genetic variation.
Is the chromosome number reduced by mitosis?
No,because mitosis is basically the movement of the organelles,during interphase (previous to the phases of mitosis) DNA is replicated and the cell grows. Although it may seem the DNA is being abolished,it isn't. DNA is actually being compacted in mitosis,not disappearing.
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.

This results in two identical copies of each chromosome, which are then separated into two daughter cells during cell division.
What is a characteristic of mitosis and not of meiosis?
The daughter cells produced are genetcally identical. A mitosis divides cells, which still contains the same number on chromosomes. In mitosis DNA is replicated once, and the nucleus divides once. In meiosis DNA is replicated once, but the nucleus is divided twice.
When do chromosomes (DNA) replicate?
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
