Abstract
Poly(U)-sepharose chromatography of RNA from bound polysomes of lactating ewe mammary gland results in the isolation of an RNA fraction containing mRNA for αs casein. Several independent experimental approaches revealed the existence of poly(A) sequences the average length of which was 130 nucleotides. Only about 40% of the messenger activity for αs casein has a poly(A) sequence.Keywords
