It is a protein structure that  protein-RNA complex called the synaptonemal complex. While autosomes always undergo synapsis during meiosis, sex chromosomes often remain unpaired. Fig. 1. Schematic diagram of the mammalian synaptonemal complex. A pair of homologous chromosomes at the zygotene stage is illustrated.

What is the synaptonemal complex? The synaptonemal complex (SC) is a meiosis-specific multiprotein complex that forms between homologous chromosomes during prophase of meiosis I. Once assembled, the SC mediates and maintains synapsis along the full length of each pair of homologous chromosomes. The major functions of Synaptonemal complex 1. Maintenance of synapsis in fixed state for an extended period for crossing over to occur.

Its position within the bivalent was initially detected by the reconstruction of serial sections under electron microscopy (EM). The synaptonemal complex (SC) is a meiosis-specific multiprotein complex that forms between homologous chromosomes during prophase of meiosis I. Once assembled, the SC mediates and maintains synapsis along the full length of each pair of homologous chromosomes. Synaptonemal complex: A protein structure that forms between two homologous chromosomes during meiosis and that is thought to mediate chromosome pairing, synapsis, and recombination. The synaptonemal complex is a tripartite structure consisting of two parallel lateral regions and a central element.

The synaptonemal complex is observed across species and promotes chromosome pairing and recombination (Page and Hawley, 2004). Moreover, assembly and disassembly of the synaptonemal complex need to be tightly regulated to ensure proper recombination and chromosome segregation.

Synaptonemal complex

synaptonemal complex A ribbon-like complex of proteins that binds together the members of each homologous pair of chromosomes during pairing (synapsis) in prophase of the first division of meiosis. Source for information on synaptonemal complex: A Dictionary of Biology dictionary.

The assembly of this structure is closely linked to  Synaptonemal complex definition is - a complex tripartite protein structure that spans the region between synapsed chromosomes in meiotic prophase. 8 Dec 2020 Homologous chromosomes pair with each other during meiosis, culminating in the formation of the synaptonemal complex (SC), which is  The bound chromatids are anchored to a complex containing SYCP2 and SYCP3 via a direct or indirect interaction with cohesin (Garcia-Cruz et al. 2010). 25 Feb 2018 1.

Sexual dimorphism in the width of the mouse synaptonemal complex

Meiosis, the cell division at the center of sexual reproduction in animals, plants or fungi promotes genetic diversity by shuffling parental chromosomes. The synaptonemal complex (SC), a highly conservedstructure built between ho-mologous meiotic chromosomes, is required for crossover formation and ensur-ing proper chromosome segregation. In many organisms, SC components can also form alternative structures, including repeating SC … Synonyms for synaptonemal complex in Free Thesaurus. Antonyms for synaptonemal complex. 57 synonyms for complex: compound, compounded, multiple, composite, manifold 2014-02-01 The synaptonemal complex (SC) 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. Synaptonemal complexes (SCs) are zipper-like structures which are assembled between homologous chromosomes during the prophase of the first meiotic division.
