The DNA sequence of the cell is not supposed to change during mitosis. There are actually "proof reading" and corrective enzymes to check for errors and correct them. However, sometimes a change does occur, and that change is called a mutation. Depending on which gene is affected, a mutation can have no effect or a devastating, life threatening effect, such as cancer.

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.
Do chromosomes undergo crossover during mitosis?
No, chromosomes do not undergo crossover during mitosis. Crossover, also known as genetic recombination, occurs during meiosis, not mitosis.
How do chromosomes align differently in meiosis compared to mitosis?
In meiosis, chromosomes align in pairs during metaphase I, while in mitosis, chromosomes align individually during metaphase.
During this stage of mitosis, when do the chromosomes become attached to the spindle fibers?
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
During which step in mitosis do the chromosomes get attached to the spindle apparatus?
During the metaphase stage of mitosis, the chromosomes become attached to the spindle apparatus.
What stage during the cell cycle are organelles and chromosomes copied?
i think its telophase
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 guide chromosomes during mitosis?
what guides the chromosomes movement during mitosis
When during mitosis do chromosomes along the equator?
Mitosis
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 .
Chromosomes form during what?
Chromosomes form during cell division, specifically during the process of mitosis. During mitosis, the chromosomes condense and line up before being separated into two daughter cells.
Do chromosomes undergo crossover during mitosis?
No, chromosomes do not undergo crossover during mitosis. Crossover, also known as genetic recombination, occurs during meiosis, not mitosis.
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.
What type of chromosomes separate during mitoses?
Both autosomes and sex chromosomes separate during mitosis./ Somatic chromosomes separate during mitosis with same number as in the parent cell.
What type of chromosome is produced during mitosis?
All chromosomes are reproduced during mitosis.
