When is every chromosome connected to a spindle fiber in mitosis?

Just after the nuclear membrane dissolves and once the chromosomes have cloned themselves to form two chromatids connected by a centomere. The spindle fibers then attach to each chromosome.

Where are chromosomes genes and DNA located?
Chromosomes are genetic information condensed from chromatin during cellular division. Chromatin is located within the nucleus of a cell, but during either mitosis or meiosis, chromosomes are formed and enter the dividing cell before reaching the equatorial plate where they are torn apart to separate daughter cells by the spindle apparatus.
Why is duplication of chromosome required before mitosis?
Because every cell in the human body contains the formula for our chromosomes. If the chromosomes don't reproduce, then new duplicate cells cannot be formed.
How is anaphase I of meiosis different than anaphase of mitosis?
In anaphase for both types of cell division, the centromeres of each chromosome separates and the spindle fibers pull apart the sister chromosomes. In mitosis, this is the shortest phase of cell division.However, the differences between mitosis and meiosis are different. Because meiosis is when chromosomes are "mixed and matched" in order to make new different combinations, the strands are only mixed up so when they split, they have new genes at their ends. Because mitosis is when chromosomes are duplicated, or cloned, and are copies of each other, when they split, the new cell is the exact same copy as the original.
Many cells in your body grow and divide every every day by what process?
Mitosis.
A human female inherits?
two copies of every gene located on the X chromosome.
How many DNA strands constitute a chromosome?
every and any DNA strand can constitue to a chromosome :)
Is mitosis taking place in us?
Every second of every day of your life
What is the number of chromosomes before mitosis?
Body cells are the only cells that go through the process of mitosis. So body cells have 46 chromosomes or 23 chromosome pairs. Before the cells separate the chromosomes duplicate and split so that the new cell has an identical DexyriboNucleicAcid.
What does every cell in every living thing come from another cell that?
has undergone mitosis
What cell has two of every kind of chromosome?
Eukaryotic Cells.
What are located on chromosomes?
Genes are located within every chromosome.
How many and which types of cells are produced from mitosis?
In mitosis two identical cells are produced. The cells that use mitosis are basically every other cell besides sex cells
