Chromosomes are thread-like structures found in the nucleus of eukaryotic cells. They consist of DNA tightly coiled around histone proteins. Chromosomes carry genetic information in the form of genes and are essential for cell division, reproduction, and inheritance. Humans typically have 23 pairs of chromosomes, totaling 46 chromosomes in each cell. This is an MCQ […]
