They also consist of large and small subunits bound together with proteins into one 70S particle. These ribosomes are similar to those of bacteria and these organelles are thought to have originated as symbiotic bacteria Of the two, chloroplastic ribosomes are closer to bacterial ones than mitochrondrial ones are. Many pieces of ribosomal RNA in the mitochrondria are shortened, and in the case of 5S rRNA, replaced by other structures in animals and fungi. In particular, Leishmania tarentolae has a minimalized set of mitochondrial rRNA. The cryptomonad and chlorarachniophyte algae may contain a nucleomorph that resembles a vestigial eukaryotic nucleus. Eukaryotic 80S ribosomes may be present in the compartment containing the nucleomorph.[citation needed] Making use of the differences The differences between the bacterial and eukaryotic ribosomes are exploited by pharmaceutical chemists to create antibiotics that can destroy a bacterial infection without harming the cells of the infected person. Due to the differences in their structures, the bacterial 70S ribosomes are vulnerable to these antibiotics while the eukaryotic 80S ribosomes are not. Even though mitochondria possess ribosomes similar to the bacterial ones, mitochondria are not affected by these antibiotics because they are surrounded by a double membrane that does not easily admit these antibiotics into the organelle. A noteworthy counterexample, however, includes the antineoplastic antibiotic chloramphenicol, which successfully inhibits bacterial 50S and mitochondrial 50S ribosomes. The same of mitochondria cannot be said of chloroplasts, where antibiotic resistance in ribosomal proteins is a trait to be introduced as a marker in genetic engineering. Common properties The various ribosomes share a core structure, which is quite similar despite the large differences in size. Much of the RNA is highly organized into various tertiary structural motifs, for example pseudoknots that exhibit coaxial stacking. The extra RNA in the larger ribosomes is in several long continuous insertions , such that they form loops out of the core structure without disrupting or changing it. All of the catalytic activity of the ribosome is carr ------------------------------ End of alt.music.moxy-fruvous digest V14 #5095 **********************************************
