In a biology lab exercise, you are asked to examine cells of a growing onion root tip, that has been sectioned to show many cell
s. in most of the cells, you easily see the circular or oval nucleus as a uniformly filled space in a membrane outline. in a small percentage of cells, you see chromosomes as distinct strands just as cell division begins, and as it progresses, because the chromatin:
Because the chromatin condenses into compacted chromosomes.
<span>During mitosis, chromatin condenses starting from the prophase to the end of cell division. Condensation of chromatin protects the DNA during cell division and facilitate its mobility and transport. </span>
