DNA replication mus occur before mitosis starts. Mitosis is another word for cell division and so there must be two copies of DNA for each cell at the end stage.

How does the cell prepares for mitosis?
A cell gets ready for mitosis through replication. Before mitosis can begin, the nucleus must make a copy of its chromatin. This ensures there is two complete sets of deoxyribonucleic acid (DNA.) This step is known as replication. When this stage occours, chromatin cannot be seen with a light microscope. The replication chromatin coils up to form double stranded chromosome, which are joined in the middle by a centromere. After replication, two complete sets of DNA are bundled up together as double stranded chromosomes. The nucleus, or "brain", of the cell is finally ready for mitosis to begin.
Before mitosis begins which happens before the nucleus starts dividing?
Before the nucleus starts dividing the process of DNA copying takes place
Mitosis starts with what?
mitosis starts with one diploid(2n) and then goes to two diploids(2n) In a human there is 46 chromosomes (23 homologous pair)
True or false replication start at one end of DNA molecule and proceeds to the other end?
False: DNA replication starts at origins of replication which can be anywhere on the DNA molecule. Replication is taking place at multiple origins at the same time.
Explain the human life cycle and the roles of meiosis and mitosis?
Ok, first you start out with the sperm fertilizing the egg, making eventually a two cell embryo. During mitosis, each embryo divides in two making four embryos. This is the process of mitosis. The embryos make up a fetus, and as the fetus develops, it comes closer and closer to birth. Finally, a baby is born and it grows into an adult. Then the adult starts the cycle all over again with the fertilization of the egg.
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.

Why do cells need to double their chromosomes before mitosis starts?
They are in need of reproduction.
What must happen to a chromosome before the next mitosis cycle starts?
i have no clie
In many this process follows mitosis?
The process that follows mitosis in cells is cytokinesis. Cytokinesis is the process of the cell dividing the daughter cell from the original cell before the process starts again.
In many cells this this process follows mitosis?
The process that follows mitosis in cells is cytokinesis. Cytokinesis is the process of the cell dividing the daughter cell from the original cell before the process starts again.
What thing is when mitosis begins?
The process of mitosis starts off with a Diploid (2N) cell.
What stages (mitosis or cytokinesis) divides the cytoplasm?
Telophase.It starts after mitosis. It divides the cytoplasm
Mitosis starts with what?
mitosis starts with one diploid(2n) and then goes to two diploids(2n) In a human there is 46 chromosomes (23 homologous pair)
What phase in a cell cycle does mitosis happen?
Normal cell activities occur not in mitosis, but in a cell cycle in a general. This part of cell cycle is called interphase. Mitosis starts when the cell starts dividing, not when a cell is carrying out normal function.
What is the word for the z shaped line that separates the DNA in DNA replication and starts with a p?
phosphate
