Spindle fibers that … WebNov 12, 2024 · Chromatids are produced from chromatin fibers during both meiosis and mitosis. Chromatin is composed of DNA and skeletal proteins and is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA enough to fit within a cell's nucleus.
