What role do spindles play in mitosis?
Spindles are protein structures that help separate chromosomes during mitosis. They attach to chromosomes and help move them to opposite sides of the dividing cell, ensuring that each daughter cell receives the correct number of chromosomes.
What are structures inside the nucleus that duplicate when a cell undergoes mitosis and separate when a cell undergoes meiosis?
Chromosomes are the structures inside the nucleus that duplicate during mitosis and separate during meiosis. Each chromosome consists of two identical sister chromatids held together by a centromere. During cell division, these sister chromatids are separated to ensure each daughter cell receives the correct number of chromosomes.
Which stage of mitosis Chromosomes decrease in length and leave the nucleus?
During prophase of mitosis, chromosomes condense and become shorter. As mitosis progresses, the condensed chromosomes move to the center of the cell and eventually separate during anaphase.
Do sister chromatids become individual chromosomes during mitosis?
Yes, sister chromatids separate and become individual chromosomes during mitosis. This process ensures that each daughter cell receives a complete set of chromosomes.
How do cells package DNA into chromosomes for mitosis in order to facilitate the movement of DNA within the cell?
Cells package DNA into chromosomes for mitosis by condensing the DNA into tightly coiled structures. This helps to organize and protect the DNA during cell division. The chromosomes then align and separate properly during mitosis, ensuring that each daughter cell receives a complete set of DNA.
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.
Chromosomes first become visible during which phase of mitosis?
They first become visible during prophase of mitosis.
What role do spindles play in mitosis?
Spindles are protein structures that help separate chromosomes during mitosis. They attach to chromosomes and help move them to opposite sides of the dividing cell, ensuring that each daughter cell receives the correct number of chromosomes.
During which portion of mitosis do the chromatids separate into chromosomes?
anaphase
What are structures inside the nucleus that duplicate when a cell undergoes mitosis and separate when a cell undergoes meiosis?
Chromosomes are the structures inside the nucleus that duplicate during mitosis and separate during meiosis. Each chromosome consists of two identical sister chromatids held together by a centromere. During cell division, these sister chromatids are separated to ensure each daughter cell receives the correct number of chromosomes.
When during mitosis when do duplicated chromosomes separate?
Duplicated chromosomes separate during anaphase of mitosis. During this phase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
Along with structures do the chromosomes line up during mitosis?
yes, during metaphase
Which stage of mitosis Chromosomes decrease in length and leave the nucleus?
During prophase of mitosis, chromosomes condense and become shorter. As mitosis progresses, the condensed chromosomes move to the center of the cell and eventually separate during anaphase.
The phase during mitosis in which DNA separates into pairs of chromosomes is?
The phase during mitosis in which DNA separates into pairs of chromosomes is called prophase. During prophase, the chromosomes condense and become visible as distinct structures before the actual separation occurs during later stages of mitosis.
Do sister chromatids become individual chromosomes during mitosis?
Yes, sister chromatids separate and become individual chromosomes during mitosis. This process ensures that each daughter cell receives a complete set of chromosomes.
How do cells package DNA into chromosomes for mitosis in order to facilitate the movement of DNA within the cell?

How many homologous chromosomes interact with each other or dont during mitosis and meiosis?
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.
