Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a eukaryotic cell is not dividing, its genetic material can be found in the form of very long thin fibers called
A
chromatin
B
chromosomes
C
the nucleolus
D
RNA
Explanation: 

Detailed explanation-1: -When a cell is not dividing, each chromosome is in the form of a long, thin chromatin fiber. Before cell division, the chromatin condenses, coiling and folding to make a smaller package. Each duplicated chromosome consists of two sister chromatids, which contain identical copies of the chromosome’s DNA.

Detailed explanation-2: -In eukaryotes, however, genetic material is housed in the nucleus and tightly packaged into linear chromosomes.

Detailed explanation-3: -In a cell which is not dividing, DNA is present as part of chromatin material. These are called chromatin because they get coloured when they are stained. Chromatin material is visible as an entangled mass of thread-like structures.

Detailed explanation-4: -Final Answer: In a non-dividing cell, DNA is present as a mass of thread-like structures known as chromatin .
