1985 June 1, Edward Brody, “The "spliceosome": yeast pre-messenger RNA associates with 40S complex in a splicing-dependent reaction”, in Science, volume 228, number 4802, page 963:
- This complex, termed a "spliceosome," is thought to contain components necessary for mRNA splicing; its existence can explain how separated exons on pre-mRNA are brought into contact.
