High sequence diversity in the RNA synthesized at the lampbrush stage of oögenesis.

چکیده
Many diverse RNA's are synthesized in the lampbrush stage oöcyte of Xenopus, as shown by the presence of different nucleotide sequences in the RNA population. This fact has been established by hybridizing lampbrush stage oöcyte RNA with an isolated nonrepetitive fraction of Xenopus DNA.

Persistence in early amphibian embryos of informational RNA's from the lampbrush chromosome stage of oögenesis.
The ripe ovarian o6cyte contains a large stockpile of informational RNA's, a direct legacy of the intense gene activity which occurs during the lampbrush chromosome stage of o6genesis. The RNA synthesized at this stage is accumulated so that in Xenopus some 47 mlig of lampbrush-synthesized, template-active RNA is finally present in the mature o6cyte.' Estimated by comparing the template activit...
متن کاملGenomic function during the lampbrush chromosome stage of amphibian oogenesis.
Throughout its lengthy developmental history the disposition of the genetic material in the amphibian o6cyte nucleus differs from that in other cell types. The chromosomes in the o6cyte nucleus, arrested for the whole of oogenesis at the prophase of the first meiotic division, are known to contain at least the tetraploid amount of DNA." 2 Odgenesis in amphibia requires months or even years to c...
متن کاملComparative bioinformatics analysis of a wild diploid Gossypium with two cultivated allotetraploid species
Background: Gossypium thurberi is a wild diploid species that has been used to improve cultivated allotetraploid cotton. G. thurberi belongs to D genome, which is an important wild bio-source for the cotton breeding and genetic research. To a certain degree, chloroplast DNA sequence information are a versatile tool for species identification and phylogenetic implications in plants. Different ch...
متن کاملHigh-resolution mapping and transcriptional activity analysis of chicken CENP-A-associated DNA sequences on giant lampbrush chromosomes
Exploration into morphofunctional organisation of centromere DNA sequences is important for understanding the mechanisms of kinetochore specification and assembly. In-depth epigenetic analysis of DNA fragments associated with centromeric nucleosome proteins has demonstrated unique features of centromere organisation in chicken karyotype: there are both mature centromeres, which comprise chromos...
متن کاملGene cloning and expression of soluble thrombopoietin functional domain by harnessing Rosetta-gami expression system
Background: Thrombopoietin (TPO) is an important cytokine that has a critical role in regulating hematopoietic stem cells (HSCs) proliferation and megakaryocyte differentiation. Because of scares amount of this protein in human plasma, in many biotechnological centers around the world, recombinant production of this protein has been carried out. This study was aiming to gene cloning and express...
