genomes , as well as their replication, transcription , and translation apparatuses. The dependence on the nuclear genome , specific features of mitochondrial transcripts , and synthesis of highly hydrophobic ...
for ultimate translation of mitochondrial genes into poly peptides. This system has proven amenable to molecular studies of not only replication and transcription but also the role of mtDNA gene pro ducts ...
of mitochondrially encoded rRNAs and tRNAs needed for translation ; a bacteriophagelike, nuclear-encoded mitochondrial RNA polymerase for transcription ; and a direct linkage between transcription and the commitment ...
The mammalian mitochondrial genome encodes thirteen oxidative phosphorylation system proteins, crucial in aerobic energy transduction. These proteins are translated from 9 monocistronic and 2 ...
genome , which is expressed by designated, mitochondrial transcription and translation machineries that differ from those operating for nuclear gene expression. In particular, the mitochondrial protein ...
metabolism, mitogenome structure and dependence of viability on the mitogenome (the petite‐negative phenotype). Transcriptions of these genomes produce only a few polycistronic transcripts , which then undergo ...
structure , and other levels of expression regulation. Key words: mitochondrial genome , recombination, transcription , expression regulation INTRODUCTION Hence mt gene expression is completely controlled ...
translation and RNA editing machineries functionally coordinate remains an open question. Contradictory results have been obtained with regard to a few mitochondrial transcripts (16–20), but a genome -wide view ...
the effect of coevolution on the mitoribosome with the mitochondrial genome . In this review, we place the new structural information in the context of the molecular mechanisms of mitochondrial translation ...
The structure , functions, and evolution of cellular organelles are reviewed. The mitochondrial genomes of eukaryotes differ considerably in size and structural organization mainly due to the length ...
