Identify the most appropriate function of chromosomes
Correct answer: C. Storage of genetic information
- A. Energy production and storage
- B. Protein synthesis and regulation
- C. Storage of genetic information
- D. Lipid metabolism and transport
Explanation
A chromosome is DNA packaged with histones, and its role is to hold the hereditary information and pass it on accurately when the cell divides. Protein synthesis is the tempting option, since genes direct it, but the synthesis itself happens on ribosomes and the chromosome only stores the instructions. Energy production belongs to mitochondria and lipid handling to the smooth endoplasmic reticulum.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
