During the "pre" version of this process in plants, a dense microtubule ring is formed around the phragmosome, known as this process's namesake band. The first time this process occurs during meiosis, synapsis leads to the formation of tetrads, and recombinant chromosomes are created through crossing over. During this stage in mitosis, asters are formed in animal cells, both the nuclear membrane and the nucleolus disappear, and two sister chromatids are connected at a centromere. For 10 points, name this stage that precedes metaphase, the first stage of mitosis.
