metagonn.

Brit.

/ˈmɛtəɡɒn/, U.S.

/ˈmɛdəˌɡɑn/

Origin: A borrowing from Greek, combined with an English element. Etymons: meta- prefix, Greek γόνος.

Etymology: < meta- prefix + ancient Greek γόνος offspring (see gono- comb. form); apparently coined by J. Gibson and G. H. Beale (see quot. 1962).

Biology.

A virus-like extranuclear RNA particle postulated to occur in certain strains of paramecium, which can infect and kill other strains.

1962 J. Gibson & G. H. Beale in Genetical Res. 3 25 As a provisional hypothesis..we proposed that the cytoplasm of mate-killer paramecia contained, in addition to the visible mu particles, certain other factors, here denoted ‘metagons’, which are assumed to be formed only in the presence of one or other of the genes M₁ and M₂.

Genetics & Cytogenetics 285 Metagon, presumably, a primary, gene-initiated product in Paramecium which is RNA (complementary to the DNA of a specific gene) in nature, conditionally stable, infectious (capable of transmission from one Paramecium to another through the cytoplasm and the external medium), and capable of replication under certain conditions.
