title: Sequence differences between mouse embryonic y- and adult beta-globin messenger ribonucleic acids.
abstract: Poly(A)-containing RNA was isolated from yolk sac cells of BDF1 hybrid mice on the 12th day of gestation. In vitro translation of the poly(A)-containing RNA by a messenger RNA (mRNA) dependent reticulocyte lysate system revealed that this RNA contained a high concentration of mRNAs from two embryonic globin chain subunits, y-1 and y-2. Cross hybridization of complementary DNA (cDNA) to the embryonic globin mRNAs with adult reticulocyte globin mRNAs and with cloned cDNAs for adult alpha- and beta-globin chain mRNAs showed that the sequence of embryonic globin y-chain mRNA differed from that of adult beta-chain mRNA.
