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.
What stage during the cell cycle are organelles and chromosomes copied?
i think its telophase
When do chromosomes (DNA) replicate?
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
What two paired cell structures are copied before mitosis begins?
Chromosomes are copied in the form of sister chromatids during S-phase of the cell cycle, which are then separated during mitosis. The centrioles also duplicate before mitosis begins to ensure proper formation of the mitotic spindle and accurate segregation of chromosomes.
When do chromosome duplicate themselves during mitosis?
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
What roles do chromosomes play in organisms?
They contain genetic information and is a form of DNA. It is copied during mitosis and meiosis.
What would result from mitosis if the chromosomes were not copied?
a nuclear explosion would take place and everything in the area would be destroyed
How many chromosomes do you have in cells before and after mitosis?
Before mitosis, cells have a diploid number of chromosomes, which means they have 46 chromosomes in humans. After mitosis, the daughter cells also have a diploid number of chromosomes, so they also have 46 chromosomes.
How many chromosomes will the daughter cells have in mitosis?
2 chromosomes
What makes copies of themselves before mitosis?
The chromosomes are copied, so that each daughter cell has an exact copy of the genetic material.
In mitosis how many times is the DNA copied?
In both mitosis and meiosis DNA replication only occurs once, during Interphase and Interphase 1, for mitosis and meiosis, respectively.
If the total number of chromosomes is six then after mitosis there will be?
After mitosis, there will still be six chromosomes in each daughter cell, as the genetic material is copied and divided equally between the two resulting cells. Each daughter cell will be genetically identical to the original cell.
