Mitochondria play a primary role in cellular energetic metabolism. They possess their own DNA, which is exclusively maternally transmitted. The relatively recent idea that mitochondria may be directly involved in human reproduction is arousing increasing interest in the scientific and medical community. ...
Though mitochondria possess their own genome and translation machinery, only a small number of mitochondrial proteins, including a few core constituents of the respiratory chain complexes, are encoded by mtDNA and synthesized within the organelle. Thus, the vast majority of mitochondrial proteins are nu...

Mitochondria possess their own genome, a circular DNA that encodes subunits of the oxidative phosphorylation (OXPHOS) complexes responsible for cellular respiration and ATP production. Mitochondrial DNA (mtDNA) is prone to mutations, including base substitutions and deletions, often leading to mitochondrial...
Although most mitochondrial proteins are nuclear-encoded, mitochondria also possess their own small genome, the mitochondrial DNA (mtDNA). To express proteins encoded in the mtDNA, mitochondria employ a specialized translation machinery including tRNAs and a mito-ribosome. Human mitoribosomes synthesize ...
to consider the structure of the mitochondria. Whereas these structures are present in all eukaryotic cells, they are not present in prokaryotes. Structurally, they resemble chloroplasts in that they each possess a double membrane system: an outer smooth membrane and an inner, much convoluted membran...
Mitochondria are roughly the size of bacteria and float in the cytoplasm of almost every cell in the human body. They possess the unique characteristic of having a double membrane which allows them to perform a number of different biochemical reactions; one of the most important is cellular respi...
Mitochondria are double-membraned organelles found in the cytoplasm of virtually all eukaryotic organisms. They contain their own genetic material, a circular chromosome termed mitochondrial DNA (mtDNA)1, differentiating them from most other eukaryotic subcellular structures with the exception of chloroplasts...
Introduction Mitochondria possess their own genome (mtDNA), which, in humans, encodes 11 mRNAs, 2 ribosomal, and 22 transfer RNAs required for the synthesis of 13 proteins of the oxidative phosphorylation complexes (Figure 1). However, this is far from being sufficient to perform all their ...
Mitochondria possess their own genome, a 16,569 bp double-stranded, circular DNA molecule (mtDNA) which encodes for 13 polypeptides of the mitochondrial respiratory chain, 22 tRNAs and 2 rRNAs required for mitochondrial protein synthesis (Fig. 1). The mitochondrial genome also contains a non-...
