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

∙ 9y agoWhen the cell has grown and replicated its DNA it is ready to divide. The chromosomes of DNA condense and coil into chromatids. The identical sister chromatids remain attached until it is time to separate the genetic material into the two new daughter cells.

∙ 9y agoIf a cell is not dividing, DNA is packaged during the stage called interphase. The chromatin within the chromosomes is less tightly packed, and this looser configuration allows transcription to take place.

∙ 14y agoIn eukaryotes DNA is first wrapped around histone proteins to form a structure known as beads on a string. These beads on a string then form a solenoid structure that forms loops and is structured into what is known as a miniband. This miniband then forms the chromosomes.

What does DNA coil up into when it is ready to divide?
In the nondividing cell, DNA tends to be a loose collection of chromatin. In the run-up to cell division, the DNA will coil itself up into distinct chromosomes.
What takes place during interphase?
The cell grows, matures, and replicates it's DNA. The cell is preparing for cell division.
Why is it impotent for DNA to be copied before cell division?
In a cell division, you need exact copy of the original cell. DNA is the blue print of the cell. You have to produce two identical copies of the original DNA. Because DNA decides every character of the cell.
Which cell division occurs after DNA replication?
DNA replication occurs just before cell division, meaning both daughter cells have DNA occurs during interphase
Why is it important that thr cell's DNA is duplicated before cell division?
If the DNA is not duplicated, then only one cell would have DNA, and a cell cannot live without DNA.
When a cell grows what phase copies its DNA and gets ready to divide?
Its called cell division
What does DNA coil up into when it is ready to divide?
In the nondividing cell, DNA tends to be a loose collection of chromatin. In the run-up to cell division, the DNA will coil itself up into distinct chromosomes.
Is DNA condensed in S phase?
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.
Durning cell division what structures do the DNA of eukaryotes bunch into?
During cell division the structures that the DNA of eukaryotes bunch into are the chromosomes.chromosomes
What takes place during interphase?
The cell grows, matures, and replicates it's DNA. The cell is preparing for cell division.
What has the instructions for cell division?
DNA
During cell division what structure of DNA of eukaryotes bunch into?
During cell division the structures that the DNA of eukaryotes bunch into are the chromosomes.chromosomes
What is the cell preparing to do in interphase?
it replicates an exact copy of the DNA within the cell and stores ATP energy ready for division
Why is it impotent for DNA to be copied before cell division?

Which cell division occurs after DNA replication?
DNA replication occurs just before cell division, meaning both daughter cells have DNA occurs during interphase
How does the cell replicate DNA?
Cells do not replicate "In DNA". Cells replicate their DNA during the process of cell division.
What happens to a cell's DNA prior to cell division?
It replicates.
