Re: Mitochondrial DNA

... encodes some of the various components for the mitochondria such as the ETC (Electron Transport Chain) proteins such as ATP synthase and it's own ribosomal genes. Here is a pretty good representation of what mtDNA looks like. http://upload.wikimedia.org/wikipedia/commons/3/3e/Mitochondrial_DNA_en.svg

Re:

... since it can make its proteins itself, my question is why does it need ribosomal proteins??? "Protein translation" probably refers to the translation of single stranded RNA into amino acids, which is usually just referred to as "translation" ...

Living or not? (viruses,viroids and prions).

sure enough but since it can make its proteins itself, my question is why does it need ribosomal proteins??? do ribosomal proteins define life???? if so, then viruses with protein coat would become living and prions too.And all other protein particles too would be ...

Re:

... in metabolism. In the last section of the Wikipedia article, about implications for definition of life, it says: They do however, lack genes for ribosomal proteins, making mimivirus dependent on a host cell for protein translation and energy metabolism. http://en.wikipedia.org/wiki/Mimivirus

Re: Theories - Origin of Life

... I also went on to state Even if a mutation occurs in the ribosome that may provide an advantage to the bacterium, it would come at a cost. Ribosomal mutations, while providing antibiotic resistance for the organism, slow the process of protein synthesis, slow growth rates, and reduce the ...
