TL;DR: Xenopus oocytes contain several mRNAs that are mobilized into polysomes only at the completion of meiosis (maturation) or at specific times following fertilization, and the dynamic process of polyadenylation, and not the length of the poly(A) tail, is required for translational recruitment during oocyte maturation.

TL;DR: Northern analysis showed that Xenopus B4 mRNA is expressed in oogenesis and embryogenesis through to the neurula stage and Sequencing of two B4 cDNA clones revealed that the predicted B4 translation product is a 29-kD protein with 29% identity with histone H1, distributed over the entire length of its sequence.

TL;DR: It is shown that genomic DNA fragments exist that contain at least 12 of these units in tandem and proposed that the different mRNA size classes vary in their number of ubiquitin coding sequences.

TL;DR: The titers of over 90 sequences isolated by cDNA cloning of oocyte poly(A)+RNA were examined during oogenesis in Xenopus laevis, finding several sequences whose titers decrease significantly during the growth phase of oogenesis as well as a few sequenceswhose titers increase slightly during this period.

TL;DR: In this paper, the authors examined the accumulation of non-polysomal maternal RNAs in polysomes after fertilization in Xenopus laevis by measuring the distributions of specific sequences in nonpolysome and polysomal fractions.
