DNA condensation is used to block the transcription and translation of a number of genes. It is part of "epigenetics" by condensation of the DNA the polymerase can no longer bind.

How do proteins help condense chromosomes?
DNA wraps around proteins that help organize and condense it.
Why is it important for the cell to duplicate DNA and other organelles before dividing?
So that the two new cells that are going to be made have an equal amount of chromosomes in them. (http://www.slideshare.net/Steven_iannuccilli/chapter-4cell-division-mitosis-dna-protein-production)
What is term for the two sets of chromatids formed in a parent cell?
sister chromatids (after DNA replication, but before dividing)
Are chromosome more condense than chromatin?
Yes, you can think of chromosomes tightly wound up DNA and chromatin as unwound DNA.
What are the names of the proteins DNA strands wind themselves around to condense into chromosomes?
Histone proteins
Before mitosis begins which happens before the nucleus starts dividing?
Before the nucleus starts dividing the process of DNA copying takes place
What do you call DNA in the nucleus before it condenses to form chromosomes?
DNA forms nucleosomes (beads on the string) by combining histone proteins, nucleosomes condense into chromatins before it forms Chromosomes
When does the DNA replicate before dividing?
In the S-phase of interphase. "S" stands for synthesis.
What is the name of the structure that DNA will condense into?
A chromosome

When does DNA begins to condense with help of structural proteins like histones?
as soon as histones are put in solution with DNA it begins to condense. Just by being there the positively charged histones are attracted to the negatively charged DNA. DNA wraps around histones and other structural proteins condensing to metaphase chromosomes.
What is the relationship between chromatin and chromosomes?
chromatin is the diffuse form chromosomes take in the nucleus of a cell when it is not dividing.
Are chromosome more condense than chromatin?
Yes, you can think of chromosomes tightly wound up DNA and chromatin as unwound DNA.
How does ethanol allow DNA strands to form?
It causes it to condense or precipitate out of the soap solution.
When is the genetic material visible in a cell?
DNA is visible during mitosis (replication) when the chromosomes condense.
