In Biology (Class 9 - The Fundamental Unit of Life), we learn that the nucleus controls the cell. Inside the nucleus are thread-like structures called chromosomes. But what exactly are they made of?
Chromosomes are made of: DNA and Proteins (Histones).
DNA: Carries genetic information.
Proteins: Help package the long DNA tightly.
Genes: Functional segments of DNA.
Chromosomes are made up of two main biological molecules:
(Think of Chromatin as an unrolled ball of wool, and Chromosomes as the wool tightly wound up.)
The functional segments of DNA on the chromosome are called genes. Genes are the specific codes that determine traits (like eye colour or blood type).
Chromosomes are made up of DNA (Deoxyribonucleic Acid) and proteins (specifically called histone proteins).
Chromosomes are found inside the nucleus of eukaryotic cells.

Why are Living Organisms Classified?
Learn why scientists classify living organisms. Class 9 Biology chapter on taxonomy, the need for classification, and how the 5-kingdom system helps study life.
Why Are Lysosomes Called Suicidal Bags?
Why are lysosomes called suicidal bags? Because they contain hydrolytic enzymes that digest the cell itself if the membrane ruptures, causing autolysis and cell death.
