Structural analysis of repetitive sequence elements transcribed in early development of Xenopus laevis
Abstract:
A cDNA library prepared from mRNA of Xenopus laevis embryos was screened with a genomic DNA fragment containing various transcribed repetitive sequence elements. Comparison of the nucleotide sequence of two isolated cDNAs and their genomic relatives allows one to define two transcribed repetitive sequence elements. One of them belongs to a highly reiterated family and consists of a tandem array of homologous subunits of 77-80 bp. The other is reiterated approximately 2200 times, has a size of 260 bp and displays a conserved region of 135 bp. The data are consistent with the presence of repetitive sequence transcripts in the 3' part of mRNA molecules.

LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...
