Question

Name the rod shaped structures present in the nucleus of the cell.

• A. Nucleosome
• B. Nucleolus
• C. Genes
• D. Chromosomes

Answer 1

The correct option is (C):

Explanation of the correct option:

1. In a non-dividing cell the genetic material is present in the form of a thread-like structure called chromatin.
   
2. During cell division, the chromatin is condensed to form a chromosome which acts as the rod-shaped structure.
   
3. This rod-shaped structure helps in the separation of genetic material in the dividing cells.
   

Explanation of the correct option:

Option (A):

1. The core of DNA-protein complex that is made out of DNA wrapped around histone proteins is called a nucleosome.
   
2. The different subunits of histone proteins form the octamer that is present at the middle of the nucleosome.
   
3. Nucleosome in the chromatin appears like beads on a string.
   

Option (B):

1. ​The nucleolus is the small circular structure that is present in the nucleus of the cell.
   
2. It acts as the region for the formation of ribosomes.
   

Option (D):​

1. Genes are the functional units of the genetic material.
   
2. These express to produce the functional products in the organism.
   

Final Answer: The rod-shaped structures present in the nucleus of the cell are called chromosomes.
