Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]

open access: yes, 2010
For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

The basic principles of DNA damage detection by the alkaline comet assay [PDF]

open access: yesArhiv za farmaciju
The Comet assay is a highly sensitive and rapid method for detecting DNA damage at the level of individual cells. It measures single-stranded and double-stranded DNA breaks, alkali-labile, incomplete excision repair and cross-linking sites.

MCM-GINS and MCM-MCM interactions in vivo visualised by bimolecular fluorescence complementation in fission yeast [PDF]

open access: yes, 2009
Background: Each of the three individual components of the CMG complex (Cdc45, MCM and GINS) is essential for chromosomal DNA replication in eukaryotic cells, both for the initiation of replication at origins and also for normal replication fork ...

Prokaryotic cells: structural organisation of the cytoskeleton and organelles

open access: yesMemorias do Instituto Oswaldo Cruz, 2012
For many years, prokaryotic cells were distinguished from eukaryotic cells based on the simplicity of their cytoplasm, in which the presence of organelles and cytoskeletal structures had not been discovered.

Nuclear magnetic resonance studies of modified eukaryotic cytochromes C [PDF]

open access: yes, 1981
The central theme of this thesis is a study of the structural changes accompanying chemical modification and denaturation of eukaryotic cytochrome c as characterised by 1II nuclear magnetic resonance (n.m.r.) spectroscopy.

Chemotaxis: a feedback-based computational model robustly predicts multiple aspects of real cell behaviour [PDF]

open access: yes, 2011
The mechanism of eukaryotic chemotaxis remains unclear despite intensive study. The most frequently described mechanism acts through attractants causing actin polymerization, in turn leading to pseudopod formation and cell movement.

The scale-free dynamics of eukaryotic cells. [PDF]

open access: yesPLoS ONE, 2008
Temporal organization of biological processes requires massively parallel processing on a synchronized time-base. We analyzed time-series data obtained from the bioenergetic oscillatory outputs of Saccharomyces cerevisiae and isolated cardiomyocytes ...

The origin of eukaryotes: the difference between prokaryotic and eukaryotic cells [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 1999
Eukaryotes have long been thought to have arisen by evolving a nucleus, endomembrane, and cytoskeleton. In contrast, it was recently proposed that the first complex cells, which were actually proto-eukaryotes, arose simultaneously with the acquisition of mitochondria.

CATALYTIC PROPERTIES OF THE EUKARYOTIC EXOSOME [PDF]

open access: yes, 2010
The eukaryotic exosome complex is built around the backbone of a 9‑subunit ring similar to phosporolytic ribonucleases such as RNase PH and polynucleotide phosphorylase (PNPase).
