In what stages of the reproductive process does meiosis occur?
in the production of eggs and of sperm the mitosis stage before the chromosomes are copied
In preparation for mitosis DNA is copied this is called DNA?
DNA is not copied during mitosis. It is copied in the portion of the cell cycle prior to mitosis during the S phase of interphase and is called DNA Replication.
What happens before meiosis?
DNA Replication. Before meiosis actually begins, the DNA that is packaged into chromosomes must be fully copied. Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy, and a paternal copy
How often do different cells undergo mitosis?
Although it varies depending on a cell (some cells never undergo mitosis), a typical cell goes through mitosis when all its organelles have been replicated, its size doubled, and its DNA copied. When all this is finished, the cell condenses its DNA and begins prophase, the first phase of mitosis.A typical cell is in mitosis only about 10% of the times, because the rest of 90% the cell is in interphase, where it goes through normal cell functions instead of dividing.
What phase is DNA duplicated?
The S phase in the interphase. Chromosomes are copied in the interphase part of the cell cycleS phase would be the answer. It is during Interphase (G1, S, G2) that they are copied. SO dependant on your answers it's either interphase or S.
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.
What stage during the cell cycle are organelles and chromosomes copied?
i think its telophase
Why are chromosome copied before mitosis?
After Mitosis, the result is 2 new, identical, daughter cells. In order for each to be identical, the chromosomes must be copied.
Can DNA be copied in mitosis?
DNA is not copied during mitosis . Mitosis is meant for division of cell and DNA is divided in two daughter cells .
What diagram models replication in which DNA is copied before mitosis occurs?
DNA duplication diagrams
When and where is DNA copied and separated?
Mitosis
In what stages of the reproductive process does meiosis occur?
in the production of eggs and of sperm the mitosis stage before the chromosomes are copied
How many chromosomes are copied in mitosis?
Once!
In preparation for mitosis DNA is copied this is called DNA?
DNA is not copied during mitosis. It is copied in the portion of the cell cycle prior to mitosis during the S phase of interphase and is called DNA Replication.
What makes copies of themselves before mitosis?
The chromosomes are copied, so that each daughter cell has an exact copy of the genetic material.
Why must a cell copy its chromosomes before it can go through mitosis?
When a cell copies its DNA, each chromosome must be copied.
What is copied during mitosis and meiosis?
A cell and its chromasomes.
