What best describes a chromosome?

Explanation:
A chromosome is a structure that contains genetic information in DNA. DNA carries the genes—the instructions for making proteins and guiding development and traits. Chromosomes organize this long DNA molecule into manageable units and ensure it can be accurately copied and distributed when cells divide, mostly housed in the cell’s nucleus. The role of chromosomes is about storing and transmitting inherited information, not performing cellular work with proteins, nor being the site of photosynthesis, nor storing energy like chemical bonds in ATP.
