<unk> hematic of the<unk>  at different stages during Prophase I A Homologous chromosomes (light blue) align and synapse together via transverse filaments (black lines) and longitudinal filaments (dark blue). Recombination nodules (gray ellipsoids) on the central region may help in<unk> ing recombination. Chromatin (red loops) is attached to its sexual leg and toe, extending from both sister chromatids. B Top: Set of tomato<unk> s. Chromatin "sheaths" visible around each<unk> . Bottom: Two tomato<unk> s with the chromatin removed, allowing kinetochores ("ball-like" structures) at centromeres to be revealed. The<unk>  <unk>  is a protein structure that forms between homologous chromosomes (two pairs of sister chromatids) during meiosis and is thought to mediate synapsis and recombination during meiosis I in eukaryotes. It is currently thought that the<unk>  functions primarily as a<unk> affold to allow interacting chromatids to<unk> e their crossover activities.
