A nascent protein remains in a complex with its ribosome and mRNA if the st
op codon is deleted from the mRNA. In the same manner mRNA forms a stable c
omplex with DNA if the transcription termination is blocked. In principle,
if both mRNA translation and DNA transcription termination are prevented, t
he protein should stay in a complex with its mRNA and DNA. A method is desi
gned to lest these possibilities. Using an immobilized luciferase gene sequ
ence, a functional luciferase protein is produced that remains associated t
hrough its mRNA with its DNA, confirming the feasibility of the proposed sc
heme. It has potential application for in vitro synthesis of proteins and p
rotein micro-arrays.
