synapsis
LowTechnical/Scientific
Definition
Meaning
The pairing of two homologous chromosomes during meiosis.
In a broader biological context, can refer to the junction between two nerve cells (synapse), though this is a distinct but related term; in genetics, specifically denotes the precise alignment of chromosomes before genetic recombination.
Linguistics
Semantic Notes
Primarily used in cell biology and genetics. Not to be confused with 'synapse' (neuronal junction), though they share an etymological root. The plural is 'synapses'.

Examples
By CEFR Level
- Synapsis is an important stage in cell division.
- The chromosomes undergo synapsis during meiosis.
- The precise mechanism facilitating synapsis between homologous chromosomes involves a proteinaceous structure called the synaptonemal complex.
- Failure of proper synapsis can lead to chromosomal non-disjunction and genetic disorders.
Learning
Memory Aids
Mnemonic
Think 'SYN' (together) + 'APSIS' (a fitting, from Greek hapsis) → chromosomes fitting together.
Conceptual Metaphor
A precise handshake between matching chromosomes.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'синапс' (synapse, the neural junction). The Russian biological term is typically 'синапсис' or 'конъюгация хромосом'.
Common Mistakes
- Using 'synapsis' to mean a neural synapse.
- Misspelling as 'synapsys' or 'sinapsis'.
- Using it as a general term for any connection.

FAQ
Frequently Asked Questions
No. While related etymologically, a 'synapse' is a junction between two nerve cells, whereas 'synapsis' refers specifically to the pairing of chromosomes during meiosis.
Its primary function is to ensure the precise alignment of homologous chromosomes, which is a prerequisite for genetic recombination (crossing over) and the subsequent correct segregation of chromosomes into gametes.
Not in standard usage. The process is described with the noun. The related verb for chromosomes is 'to synapse' or 'to pair'.
It is a core term in genetics, molecular biology, and cell biology, particularly in the study of meiosis and heredity.
