Comparative aspects of animal oogenesis.
All metazoans that reproduce sexually have the ability to form gametes. Both types of gametes, the egg and the sperm, arise from germ cells, undergo a unique program of differentiation, and are destined to unite. The outcome of their union, the zygote, is a cell possessing the tremendous potential to build a new individual that expresses, maintains, and propagates characteristics of the species...
متن کاملComparative aspects of animal regeneration.
Most but not all phyla include examples of species that are able to regenerate large sections of the body plan. The mechanisms underlying regeneration on this scale are currently being studied in a variety of contexts in both vertebrates and invertebrates. Regeneration generally involves the formation of a wound epithelium after transection or injury, followed by the generation of regenerative ...

متن کاملMolecular aspects of avian oogenesis and fertilisation.
In this paper, we summarise studies which have been carried out on the metabolism of nucleic acids (maternal RNA, DNA, nucleolytic enzymes) in avian oocytes and embryos (Japanese quail, Coturnix coturnix japonica ) within the last 10 years in the Institute of Genetics and Animal Breeding of the Polish Academy of Sciences. The accumulation of maternal RNA in the quail oocyte during oogenesis is ...
متن کاملThe Drosophila LIN54 homolog Mip120 controls two aspects of oogenesis
The conserved multi-protein MuvB core associates with the Myb oncoproteins and with the RB-E2F-DP tumor suppressor proteins in complexes that regulate cell proliferation, differentiation, and apoptosis. Drosophila Mip120, a homolog of LIN54, is a sequence-specific DNA-binding protein within the MuvB core. A mutant of Drosophilamip120 was previously shown to cause female and male sterility. We n...
