eukaryotic cell

a cell with a true nucleus. See also cell.

eukaryotic cell

The type of cell composing multicellular, as well as a number of unicellular, organisms. Unlike prokaryotic cells, eukaryotic cells have many of their intracellular functions organized within structures called organelles. Some organelles -- notably, the nucleus, which contains the DNA -- are enclosed by intracellular membranes.

Finally, an examination of "eukaryotic signature proteins," in the organelles of eukaryotic cells has shown that the proteins of eukaryotic cells are not simply admixtures of sequences from archaea and eubacteria, but are, in many cases, unique in their own right.
These derived features and their consequences for selection on the eukaryotic cell (the host and the clonal mitochondrial population) and perhaps on even higher level units (eukaryotic populations and species) determined which host-symbiont association succeeded and which failed.
The inside-out theory is radically different from all existing theories because the action in building the eukaryotic cell is outside the boundaries of the ancestral cell.
Our new understanding that aging may ultimately be traceable to a relatively small number of molecular mechanisms common to all eukaryotic cells will almost certainly speed the pace of aging research in coming years.

If most or all of the groups assigned to the Archezoa are secondarily amitochondriate, then it significantly reduces our ability to present detailed and testable models of the sequence of innovations that led to the eukaryotic cell.
The D-Pop Kit is used to capture these DNA-containing particles from cell-free biological samples such as blood serum and plasma, urine, and eukaryotic cell culture media, and to extract DNA from the captured particles.
According to his calculations, about 98 percent of the RNA produced in a eukaryotic cell don't encode a protein.
Cell-free fluids that can be processed with the ExoMir Kit include blood serum, cerebrospinal fluid, and eukaryotic cell culture media.
The plasma membrane of a eukaryotic cell is the site of communications between the cell and its environment through endocytosis--where different membrane-coated vesicles that constantly bud off the plasma membrane enter the cytoplasm--and exocytosis--where vesicles arrive from the cytoplasm and fuse with the plasma membrane.
