Describe the chromatic that make up a chromosome when a cell is ready to split
the correct answer is 25
Mitosis?
Chromosomes can be seen during cell divison, Reference Before a cell gets ready to divide by mitosis, each chromosome is duplicated (during S phase of the cell cycle
At every few intervals,about 5 histones are used to pack DNA.Histones are spherical proteins. http://www.gistsupport.org/learning-center/cells-cancer-and-more/how-dna-is-packaged-in-a-cell.php
When cells are not actively dividing, the DNA just looks like grainy blobs.
centrioles. during mitosis in animal centrioles are used for division to create spindle fibers to move and connect the chromosomes/chromatids. In plants the spindles are all ready in the cell and do not need to be produced so no centrioles are necessary.

When a cell is getting ready to divide, the DNA will coil itself with the help of proteins into a chromosome.
Anaphase 1: Before Meiosis begins, each chromosome is duplicated, like in Mitosis. When the cell is ready for meiosis, each duplicated chromosome is visible under the microscope as two Chromatids. Anaphase 2:The two cells formed during Meioses 1 now begin Meiosis 2. The chromatids of each duplicated chromosome will be separated during this division. (Anaphase also means Meiosis. Meiosis 1 and Meiosis 2 for instance. i hoped this helped!)
Chromatin and chromosomes are basically the same thing. The difference is that chromatin is unfolded, uncondensed, extended DNA while chromosomes are condensed DNA. Chromosomes are condensed chromatin and chromatin is unfolded chromosomes. The only difference I know is that chromatin are present normally in a cell, while chromosomes are there only when the cell is about to divide. When the cell is about to divide, the chromatin threads get organised into chromosomes. Utilizing their histone proteins to accomplish this, DNA first condenses into 10 nm strands and then into 30 nm strands, ready for Condensation and then Cytokinesis.

DNA is duplicated in the S phase because in the G1 phase the cell is growing and not yet ready to divide, then DNA copies as the first step for when it is getting ready to divide. In the G2 phase the cell continues to get ready to divide once the DNA is copied.
