WebApril 10, 2024. Sperm must swim swiftly to an egg in order to fertilize it, and so they have evolved hydrodynamic shapes. Most of the space in the head of sperm cells is taken up by the DNA they carry, so the cells coil up their DNA super tightly to stay small and streamlined. In most cell types, DNA is coiled around proteins called histones. WebApr 25, 2024 · DNA is so long that the helical coil itself becomes like a big fiber, which can be coiled again. The density of a chromosome is like that of many cords coiled into a circle and stacked together in large crates, …

WebFigure 12.2. 4: Double-stranded DNA wraps around histone proteins to form nucleosomes that have the appearance of “beads on a string.”. The nucleosomes are coiled into a 30-nm chromatin fiber. When a cell undergoes mitosis, the duplicated chromosomes condense even further. DNA replicates in the S phase of interphase. sporting goods marianna fl
