The synaptinemal complex and four-strand crossing over.
نویسنده
چکیده
The synaptinemal complex provides a structural basis for four-strand crossing over: prior to chromosome pairing, both sister chromatids of each homologous chromosome participate in the genesis of one lateral component. During precise pairing, the two lateral components are combined into one synaptinemal complex per bivalent.

The Fine Structure of Meiotic Chromosome Pairing in the Triploid, Lilium Tigrinum
The elongate tripartite structure of synapsed homologous chromosomes at meiotic prophase was described by Moses (7) and by Fawcett (2) in 1956. A functional interpretation of this synaptinemal complex was put forward by Moses in 1958 (8) and by Coleman and Moses in 1964 (1). They proposed that the complex is "the morphological expression of the specific function of the pairing of homologous chr...

Meiosis within fruiting bodies of Coprinus lagopus Fr. is closely synchronized. This conveniently facilitates joint lightand electron-microscope observations. Before nuclear fusion the chromatin appears diffuse in the light microscope; after nuclear fusion individual chromosomes can be recognized. In the electron micrographs the chromatin of pre-fusion and early fusion nuclei cannot be recogniz...
متن کاملStudies on the Mechanism of Crossing over.
N E of the major objections to the torsion theory of crossing over as pro-0 posed by DARLINGTON (1935) is that it is difficult to comprehend why a break in one chromatid should cause a break to occur in exactly the same position in a chromatid from the homologous chromosome. This objection holds for any mechanism which postulates that crossing over occurs after the duplication of the chromosome...

Reconstruction of serially sectioned zygotene and pachytene nuclei has allowed the estimation of both the number and position of central component recombination nodules in the synaptinemal complexes of two chromosomally different strains of Neurospora crassa. In both strains the number of nodules is that expected if each nodule represents one crossover event (50 map units). The distribution of ...
متن کاملAn Experimental and Theoretical Study of Chromatid Crossing over.
The term “crossing over” is used to denote the exchange of pieces or segments between homologous chromosomes. There are many facts which indicate that the exchange of parts or segments occurs during the first meiotic prophase when the two homologous chromosomes are in intimate association. Prior to 1916 crossing over was thought to take place between the two paired chromosomes before they had d...
