Figure 21-5 A more complete outline of the biosynthesis of triacylglycerols, glycolipids, and phospholipids including characteristic eukaryotic pathways. Green lines indicate pathways utilized by both bacteria and eukaryotes. Structures of some of the compounds are shown in Fig. 21-4. The gray arrows show the formation of phosphatidylserine by exchange with ethano-lamine (Eq. 21-10).

Discuss the changes that must be made in a typical eukaryotic structural gene to allow its protein product to be synthesized in bacteria. 

In this chapter I present phylogenetic data which are consistent with an endosymbiotic origin of what subsequently became the nucleus. Subsequently means here that the nucleus, as well as other typically eukaryotic structures, emerged after the advent of aerobically respiring mitochondria. A concept of canonical pattern of mitochondrial ancestry for eukaryotic genes (Emelyanov 2001b, 2003b) will be shown to be crucial to the issue. 

Taken together, the data presented here suggest that the emergence of typically eukaryotic structures - the nucleus, the endomembrane system, and... 

The only eukaryotic structures that contain DNA are the nucleus and the mitochondria. In mitochondria there is one chromosome in the nucleus, many chromosomes. 

To illustrate the complexities of ion channels, there is recent evidence that the bacterial CIC channel is actually an H+/C1 transporter (Accardi and Miller, 2004). The bacterial and eukaryotic structures do possess strong similarity, however, and the eukaryotic case ClC-0 is indeed a true channel (Chen and Chen, 2001). 

Traces of the other nucleic acid, RNA, have been found in the basal bodies of cilia and flagella. This evidence is considered by some researchers to support the idea that such eukaryotic structures arose by a symbiotic union.
