What are the thread-like structures carrying genetic information in the form of genes in eukaryotic cells called?

💡 Solution & Explanation

Chromosomes are highly organized thread-like nuclear structures composed of tightly coiled DNA double helices wrapped around histone proteins, serving as the primary vehicle for hereditary traits in eukaryotic cells. Ribosomes function as protein synthesis machinery, whereas lysosomes contain hydrolytic enzymes for intracellular digestion. During cellular division, chromosomes ensure accurate replication and distribution of genetic material to daughter cells. Every eukaryotic species maintains a characteristic chromosome number within its somatic cells.
