Why is it important that the cell's DNA is duplicated before cell division? Why can plasmids replicate independently of the bacterial chromosome? What are the similarities between prokaryotes and eukaryotes? Why do mitochondria have their own DNA?
In animal cells, mitochondria are semiautonomous organelles of virtually "hostile" (bacterial)norigin, with their own code and genome (mtDNA). The semiautonomy and restricted resourcesncould result in occasional "conflicts of interests" with other cellular components, in whichnmitochondria have greater...
Perhaps some mitochondrial proteins (mitoproteins) are more amenable to being retargeted to mitochondria after nuclear transfer. To determine how many nucleus-encoded mitoproteins have detectable N-terminal mitochondrial targeting signals (MTSs), we used a number of programs to predict MTSs in genes en...
Why do mitochondria have their own DNA? How does DNA structure allow for DNA sequencing? In decoding DNA, how are bases identified (i.e. do T, G, A and C look different under an electron microscope)? What is the difference between DNA replication and transcription? Compare and con...
A new study suggests why mitochondria—the powerhouses of the cell—still hang on to tiny genomes of their own. These organelles originated more than a billion years ago as single-celled organisms that were swallowed by larger cells. Since then the mitochondrial genome has shrunk, with many gen...

MITOCHONDRIAORGANELLESObjectives: Nasal polyposis (NP) is an inflammatory disease of the nasal mucosa and paranasal sinuses. Mitochondria are the cellular organelles which produce cellular energy by Oxidative Phosphorylation (OXPHOS), and they have own inheritance material, mtDNA....

Do eukaryotes have single-stranded DNA? Does ribosomal RNA use ATP? Does prokaryotes or archaea have a mitochondria? Are ribosomes made entirely of ribosomal RNA? Ribosomes - are not found in prokaryotes. - carry genetic information. - carry out translation. - contain RNA only. - None of th...
other hand, are extremely interested in nucleotides. While they have various nucleotide salvage and repair pathways on hand, demand is high—mitochondrial DNA is constantly subjected tomutations and partial deletions, it must be continually refreshed as mitochondria replicate themselves and their nucleoid...
