Synaptonemal Complex (SC) is a molecular structure that forms during the prophase I stage of meiosis, and is essential for the accurate pairing and segregation of homologous chromosomes. Synonyms for the term Synaptonemal Complex include "crossing-over apparatus," "synaptic ladder," and "meiotic chromosome cores." Additionally, SC is also referred to as "synapsis helper," "chromosome condensation complex," and "chromosomal synapsis machine." These synonyms more accurately describe the function of SC in meiosis, highlighting its role in facilitating the exchange of genetic material between homologous chromosomes. Though the terminology may differ, the importance of understanding the Synaptonemal Complex remains consistent in the study of genetics and reproductive biology.
