Definition of synaptonemal complex in English:
synaptonemal complex
nounsɪˌnaptə(ʊ)ˈniːm(ə)lsʌɪ-səˌnaptəˌnēməl ˈkämpleks
Biology A ladder-like series of parallel threads visible in electron microscopy adjacent to and coaxial with pairing chromosomes in meiosis.
Example sentencesExamples
- The nucleus reorganizes during this time, as sister chromosomes pair and the synaptonemal complex forms.
- Despite no or reduced exchange, both mutant alleles have normal synaptonemal complex.
- The early gene family encodes factors required for meiotic DNA replication, chromosome pairing, synaptonemal complex formation, and meiotic recombination.
- The synaptonemal complex is present at this stage, and meiotic recombination is completed within this context.
- In the absence of recombination, it has been suggested that the synaptonemal complex may assume this role in some organisms.
Origin
1950s: from synapto- (combining form of synapsis) + Greek nēma 'thread' + -al.
