What is chromatin, and what happens to chromatin during cell division?
A
Chromatin is DNA in the form of a short strand. During cell division, chromatin strands coil and condenses into thick structures called chromosomes.
B
Chromatin is DNA in the form of a long strand. During cell division, chromatin strands coil and condenses into thick structures called chromosomes.
C
Chromatin is DNA in the form of a short strand. During cell division, chromatin strands coil into thick structures called chromosomes.
D
Chromatin is DNA in the form of a long strand. During cell division, chromatin strands condenses into thick structures called chromosomes.
E
Chromatin is DNA in the form of a long strand. During cell division, chromatin strands coil and condenses into short structures called chromosomes.
Explanation: 

Detailed explanation-1: -Each chromosome consists of a single, enormously long linear DNA molecule associated with proteins that fold and pack the fine DNA thread into a more compact structure. The complex of DNA and protein is called chromatin (from the Greek chroma, “color, ” because of its staining properties).

Detailed explanation-2: -Chromatin condenses to form chromosomes during cell division. They are both essentially the same thing, but with a different structure. Chromatin is a network of fibers that contains the genetic information whereas the chromosomes are a more condensed version of the same thing.

Detailed explanation-3: -During mitosis, chromosomes condense and many transcription factors and chromatin binding proteins are ejected from the chromatin.

Detailed explanation-4: -What Is Chromatin? Chromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell.

Detailed explanation-5: -They are composed of DNA and protein. Chromatin material is entangled mass of thread-like structures. Chromatin material gets organized into chromosomes, just before the cell divides. Was this answer helpful?
