摘要: Abstract The initial interaction between a natural messenger RNA and ribosomes in eukaryotic system was studied. Utilizing population of 1.0 M KCl-washed isolated myosin mRNA, only the 40S subunits bound mRNA to form initiation complex I. This binding required presence factor EF 3 either GTP or its analogue, GDPCP. When unfractionated factors, tRNA were added reaction mixture, 60S ribosomal subunit joined with I produce II. Complex II could not be demonstrated absence when replaced by
