HeLa human cells were injected with a natural mixture of rabbit alpha and beta globin
mRNA. They were incubated for 6 hr with [35S] methionine either immediately after injection …

The translations of native messenger RNA for rabbit globin and that of poly (A)-free globin
messenger RNA have been compared after injection into Xenopus oocytes. The initial rate …

Rabbit globin poly (A)-free and native mRNA preparations were microinjected into Xenopus
oocytes. The amount of globin message remaining after incubation of injected oocytes was …

A specific method has been developed for the removal of polyadenylic acid-rich sequences
from messenger RNA. The method is based on the processive phosphorolysis of mRNA …

The size of the polyadenylic acid region of newly synthesized globin mRNA was determined
on mRNA isolated from nucleated erythroid spleen cells of anemic mice. The globin mRNA …

Nucleated erythroid cells isolated from the spleens of anemic mice were used to investigate
the processing of the polyadenylic acid region of globin mRNA. Cells were labeled in media …

Human globin messenger RNA (mRNA) prepared from erythroid cells of patients with sickle
cell anemia has been translated in Xenopus laevis oocytes. Addition of hemin to the injected …

The stability of messenger RNA for rabbit and mouse α and β globin has been tested by
injection into living frog oocytes, which were subsequently cultured for up to two weeks.[3 H] …

Rabbit globin mRNA species containing poly (A) segments of different lengths were
prepared by partial phosphorolysis of mRNA with Escherichia coli polynucleotide …
