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.

What is a chromosome in its condensed form called?
Chromatin
What makes the chromosomes become visible during prophase?
When pro phase begins, the DNA molecules are progressively shortened and condensed by coiling, to form visible chromosomes.
What is the condensed form of DNA referred as?
The highly condensed forms of DNA (and proteins) are known as chromosomes.
What is threads of condensed DNA?
The threads, chromatin, are coiled into a tight dense mass of DNA to form a chromosome.
What are the highly condensed portion of chromatin which appear as very dark areas in a transmission electron micrograph?
which is the loosely condensed chromatin where genes are expressed
What is a chromosome in its condensed form called?
Chromatin
Where chromosomes are present?
Chromosomes are thick,condensed, ribbon-like structures which are visible within the nucleus at the time of cell division. They are the condensed form of chromatin fibres which are present in the nucleoplasm of the nucleus.
Is it in telophase that the chromosomes assume their less condensed chromatin form?
It's TrueTrue
In interphase the DNA in the form of loose threads called?
During interphase, the DNA of a cell uncoils from its highly condensed chromatid form to become chromatin, long, thread-like structures.
What is it called when DNA is scrunched up in dividing cells?
Chromatin, if "scrunched up" refers to uncoiled. It is chromosomes not chromatin

Doubled rod of condensed chromatin?

What form is DNA during interphase?
During interphase the DNA is in loose form. It makes the chromatin inside the nucleus. The chromatin allow access to RNA and DNA polymerases that transcribe and replicate DNA.During interphase the DNA is in loose form. It makes the chromatin inside the nucleus.

What uncoiled dna like thread?
Chromatin is the uncoiled form of DNA that resembles a thread-like structure. It consists of DNA wrapped around proteins called histones, which help organize and compact the DNA into a condensed form. When DNA is uncoiled and in the form of chromatin, it allows for easier access and transcription of the genetic information stored in the DNA.
