What else can I help you with?
What process does not occur in the chromosome between mitosis 1 and mitosis 2 that causes the chromosome number to be reduced?
Between mitosis I and mitosis II, DNA replication does not occur. This absence of DNA replication means that the chromosomes, which have already been duplicated during the S phase prior to mitosis I, do not replicate again. As a result, when the cells divide during mitosis II, they separate the sister chromatids, leading to a reduction in chromosome number, effectively halving it from the original diploid state to haploid.
What process can Genetic changes in mitosis can only occur by?
Genetic changes in mitosis can only occur through mutations, which are changes in the DNA sequence. These mutations can be caused by errors during DNA replication, exposure to mutagens like radiation or chemicals, or spontaneous changes in the DNA.
Does chromosome replication occur in mitosis and meiosis?
Chromosome replication occurs before both mitosis and meiosis. During the S phase of the cell cycle, DNA is replicated in preparation for cell division. In mitosis, replicated chromosomes are separated into two identical daughter cells, while in meiosis, replicated chromosomes are separated twice to produce haploid gametes.
How does a pair of sister chromosome differ from a single unduplicated chromosome?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
How does a single pair of sister chromatids differ from a single unduplicated chromozone?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
What is the structure of mitosis?
Structures of mitosis include chromosomes, chormatids, centrioles, chromosome, and spindles. basically the things that are made and used for mitosis to occur

How many rounds of chromosome replication occur in the cell?
One round of chromosome replication occurs in the cell during the S phase of the cell cycle. This results in each chromosome being duplicated, producing two identical DNA molecules called sister chromatids that are connected at the centromere.

What important changes occur to the chromosomes and the nucleus of prophase of mitosis?
something very important
How does a single pair of sister chromatids differ from a single unduplicated chromozone?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
Does mitosis allow genes to move from one chromosome to another?
No, mitosis does not allow genes to move from one chromosome to another. Mitosis is a type of cell division that results in two daughter cells each having the same number and type of chromosomes as the parent cell. Genes are not moved between chromosomes during this process.
Must mitosis occur in budding?
Mitosis must occur in budding.
Where in the cell does most of the activity occur doing mitosis?
Most of the activity during mitosis occurs in the nucleus, where the duplicated chromosomes condense, align, and separate. The microtubules that form the spindle apparatus and help in chromosome movement also play a key role in mitosis. Additionally, the cytoplasm is involved in providing the necessary cellular components and energy for the process to occur.
