Embryonic axis specification in nematodes: evolution of the first step in development
In 1828, von Baer proposed that the early stages of development must be the most conserved [1]. Others have since countered that the middle stages of development are the most conserved [2]. To address whether the earliest step in pattern formation can evolve, we have examined how asymmetry along the antero-posterior (AP) axis is generated in various nematode species. AP asymmetry is specified i...
متن کاملdevelopment of feminist poetics in adrienne rich
اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...
15 صفحه اولEvolution of development in nematodes related to C. elegans.
The knowledge about C. elegans provides a paradigm for comparative studies. Nematodes are very attractive in evolutionary developmental biology given the species richness of the phylum and the easiness with which several of these species can be cultured under laboratory conditions. Embryonic, gonad, vulva and male tail development were studied and compared in nematodes of five different familie...
متن کاملEvolution of mitotic spindle behavior during the first asymmetric embryonic division of nematodes
Asymmetric cell division is essential to generate cellular diversity. In many animal cells, the cleavage plane lies perpendicular to the mitotic spindle, and it is the spindle positioning that dictates the size of the daughter cells. Although some properties of spindle positioning are conserved between distantly related model species and different cell types, little is known of the evolutionary...
متن کاملEvolution of small nucleolar RNAs in nematodes
In contrast to mRNAs, which are templates for translating proteins, non-protein coding (npc) RNAs (also known as 'non-coding' RNA, ncRNA), exhibit various functions in different compartments and developmental stages of the cell. Small nucleolar RNAs (snoRNAs), one of the largest classes of npcRNAs, guide post-transcriptional modifications of other RNAs that are crucial for appropriate RNA foldi...
