👉 Microchromosome is a type of chromatin structure that is found in eukaryotic cells, particularly in the nucleus. It consists of two copies of a single DNA molecule, each containing only one strand. Unlike other types of chromatin, which can contain multiple copies of the same DNA sequence, microchromosomes consist of only one copy of the DNA. Microchromosomes are essential for the regulation of gene expression and have been identified in various organisms, including humans, mice, and plants.
