so that there will be two sets of DNA ... one for each new cell. If the DNA doesnt replicate one new cell would have no DNA. and cells need DNA.
Yes. In meiosis, the DNA is replicated once and the cell divides twice.
DNA is replicated during the S phase of the cell cycle, which occurs before cell division. The precise timing of DNA replication can vary depending on the cell type and the specific stage of development.
If you are referring to cell division, this is most commonly mitosis, in which the cell replicates its organelles, and then divides. However, there is also meiosis, in which the organelles are not replicated before division, thus resulting in a gamete or sex cell (eggs/sperm).
Because each cell needs its own set of DNA, there must be two sets of DNA present in a cell before it divides into two.
The chromosomes have to split and go to opposite sides of the cell.
so that when the cell divides each new cell has a full copy of the DNA
the DNA poly-meres must add complementary nucleotides to the DNA
Yes. In meiosis, the DNA is replicated once and the cell divides twice.
Because it is the system by which plants and animals grow.When the cell divides a complete copy of the first cell's DNA must be replicated in the new cell.
DNA is replicated during the S phase of the cell cycle, which occurs before cell division. The precise timing of DNA replication can vary depending on the cell type and the specific stage of development.
Your DNA is copied into the new cell every time it divides
in mitosis a parent cell divides into two daughter cells in which the chromosomes are replicated and distributed equally into daughter cells. while in meiosis a parent cell divides into four unequall daughter cells.
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.
If you are referring to cell division, this is most commonly mitosis, in which the cell replicates its organelles, and then divides. However, there is also meiosis, in which the organelles are not replicated before division, thus resulting in a gamete or sex cell (eggs/sperm).
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
During interphase, DNA is replicated. This process ensures that each cell will have a complete set of genetic information before cell division occurs.
Chromosomes are formed from condensed chromatin as a cell divides during mitosis. Chromosomes are the structures that contain the genetic material (DNA) and are replicated and divided equally between the daughter cells to ensure proper genetic inheritance.
