eucaryotic cell

The production of a protein by a eucaryotic cell.

Eucaryotic cells have at least two major families of molecular chaperones-known as the hsp60 and hsp70 proteins.

A typical eucaryotic cell contains millions of ribosomes in its cytoplasm (Figure 6-62).

In most eucaryotic cells, genes consist of mingled exons and introns.

The final level of each protein in a eucaryotic cell depends upon the efficiency of each step depicted.

The appearance of the first eucaryotic cells in the fossil record were relatively followed by evidence of complex multicellular life.

Quinolones also appear to effect the growth of eucaryotic cells and HeLa cells.

However, relatively high doses of quinolones (20 ug/ml) are required to impair eucaryotic cell growth.

Not even what Lynn Margulis had encountered with the theory of symbiotic evolution of eucaryotic cells.

Another laboratory separation tool is the immunomagnetic separation (IMS), which is more suitable for the isolation of eucaryotic cells.

For example geochemical features of rocks may reveal when life first arose on Earth, and may provide evidence of the presence of eucaryotic cells, the type from which all multicellular organisms are built.

DNA in eucaryotic cells is arranged in two interwoven strands-the "double helix"-and packed tightly into a complex structure called chromatin, which is arranged into chromosomes in each cell nucleus.

Some of the more common antibiotics of this kind are listed in Table 6-3 along with several other inhibitors of protein synthesis, some of which act on eucaryotic cells and therefore cannot be used as antibiotics.

In a eucaryotic cell, for example, chloramphenicol inhibits protein synthesis on ribosomes only in mitochondria (and in chloroplasts in plants), presumably reflecting the procaryotic origins of these organelles (discussed in Chapter 14).

After the exhaustion of most primordial inorganic oxygen sinks about 2 billion years ago (Cloud, 1976; Schopf, 1978) and the development of the eucaryotic cell and oxygenic photosynthesis, the major environments of the world began to turn from predominantly reducing to predominantly oxidizing conditions.

Ribosomes operate with remarkable efficiency: in one second, a single ribosome of a eucaryotic cell adds about 2 amino acids to a polypeptide chain; the ribosomes of bacterial cells operate even faster, at a rate of about 20 amino acids per second.

The GFP gene has been introduced and expressed in many procaryotic and eucaryotic cells and the Nobel Prize in Chemistry 2008 was awarded to Martin Chalfie, Osamu Shimomura, and Roger Y. Tsien for their discovery and development of the green fluorescent protein.
