Pushing and Pulling: Microtubules Mediate Meiotic Pairing and Synapsis

Meiotic pairing in the nematode Caenorhabditis elegans is facilitated by chromosomal sites known as pairing centers that are tethered to the nuclear envelope. and provide insight into how proteins linking pairing centers and the microtubule cytoskeleton mediate homolog pairing and restrict synapsis to homologous pairs of chromosomes.
