Heterochromatin
Heterochromatin is a tightly packed form of DNA or condensed DNA, which comes in multiple varieties. These varieties lie on a continuum between the two extremes of constitutive heterochromatin and facultative heterochromatin. Both play a role in the expression of genes.

∙ 10y agoActually the double stranded (ds) Dna molecule in isolation is quite ridgid and brittle - not quite threadlike. Also and actually the extended Dna of our Human Chromosome {yes, 46 total placed in 23 pairs} is 1.87 meters in linear length. Within the nucleus is the other Situation.
Defining the [prokaryotic and eukaryotic] chromatin strand as a 20 nanometer wide strand of duplex (ds) Dna, the following occurs only in Eukaryotes - this twenty nanometer strand has an extremely high affinity for Histone Proteins that it wraps around and forms histone cores. These then proceed through more coiling to form The Ten Nanometer Fiber and without interruption coil again on somewhat of an internal basis to coalesce to form The Thirty Nanometer Fiber we see as the Chromosome.

What does Chromatin condense of?
Chromatin can't "condense of" anything, chromatin can condense into Chromosomes.
During cell reproduction the chromosomes condense from the that is normally found in the nucleus?
Chromatin Chromatin
The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is the?
The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is Interphase. Interphase is the first stage of the cell cycle.
Why does chromatin condense to form chromosomes?
Cells condense their chromatin into chromosomes only when cell division is occurring
Does the cells chromatin condense into chromosomes during prophase?
yes, during prophase
What does Chromatin condense of?
Chromatin can't "condense of" anything, chromatin can condense into Chromosomes.
When a cell divides do the chromatin condense into chromosomes?
Yes, they do

Why does chromatin condense to form chromosomes?
Cells condense their chromatin into chromosomes only when cell division is occurring
Does the cells chromatin condense into chromosomes during prophase?
yes, during prophase
During which phase does the chromatin condense into chromosomes?
The chromosomes coil up and condense during prophase
Are chromosome more condense than chromatin?
Yes, you can think of chromosomes tightly wound up DNA and chromatin as unwound DNA.
When do chromatin threads appear as chromosomes?
During prophase, chromatin threads condense,coil, shorten and thicken into chromatids, but how do the chromsomes of parent cells turn into the chromatin threads
During which phase do the chromatin fibers condense and shorten into chromosomes that are visible under the microscope?
PROPHASE
Genetic material found in the nucleus during interphase?
chromatin
In what stage of mitosis does the chromatin coil and condense to form deeply staining bodies?
The chromosomes condense during prophase, the first stage of both mitosis and meiosis.
