THE microinjection technique perfected by Gurdon and his collaborators 1,2 represents an excellent method for the study of the in vivo effects of drastically changing the molecular contents of the injected cells. We have ...

Wheat protein synthesis elongation factor 1 was tested for binding to GTP analogs, including structures resembling "caps" that are present at the 5′-termini of most eukaryotic mRNAs. The interaction was assayed by determining ...
