What is a cell making a copy of its DNA called?

Answer 1

the cell makes a copy of its DNA before starting mitosis because, as organisms grow and change, they need new cells to make more skin tissue, bone tissue, muscle tissue. These new cells can only come from one place other cells- through the process of cell division, or mitosis.

• For multicellular organisms (like us) cell division allows an organism to grow and develop from a single cell to trillions of cells, to repair and replace cells worn out and used up by everyday life, and in some cases, to make specialized cells for reproduction.

So each cells have the same DNA but half the organelles that one cell have.

Add: DNA replication results in two identical copies of each chromosome. There needs to be two copies of each chromosome so that at the end of mitosis each daughter cell has the exact same number and types of chromosomes as the original cell. In other words, the daughter cells must have the exact same DNA as the original cell.

Answer 2

Yes, it does. The first step is Interphase, when the cell is growing and developing. It is the first step of mitosis. Prophase, the second step, is when the cells chromosomes double and the cell membrane get sucked into the cell. In Metaphase, the chromosomes line up down the center of a cell. Anaphase is the part when the chromosomes cluster at separate ends of the cell and they start to split apart. The second-to-last step, Telophase happens as a faint cell wall starts to form in between the two separating cells, and finally Cytokines is when you have two small separate cells.

P.S. I know I probably sound like a nerd, but i saw this question and answered it since I'm learning this stuff in science. (:

Answer 3

No. Mitosis is strictly the stage of the cell cycle where the chromatin condenses into chromosomes, the nuclear envelope dissolves, the chromosomes line up on the metaphase plate, spindly fibers attach to the kinetochores of each chromosome and "pull" sister chromatids apart to opposite poles of the cell. Then the cell pinches off and forms a nuclear envelope around the DNA. The stage in the cell cycle where a cell duplicates its genetic material is called the S phase, preceded by the G1 phase, followed by the G2 phase, then mitosis and cytokinesis.

Answer 4

A cell making a copy of its DNA is called DNA replication. During this process, each strand of the DNA molecule serves as a template for the creation of a new complementary strand. This ensures that each new cell receives an exact copy of the genetic information needed for cell division and growth.

Answer 5

Each cell needs its own set of DNA. Mitosis occurs before a cell can divide so each cell can have its own nucleus, with its own DNA.

Answer 6

process called meiosis
