Mitochondria are thought to have originated from free-living prokaryotic organisms, specifically alpha-proteobacteria, which were engulfed by ancestral eukaryotic cells in a symbiotic relationship. This event, known as endosymbiosis, allowed the host cell to utilize the bacteria's ability to produce energy through oxidative phosphorylation. Over time, these engulfed bacteria evolved into the mitochondria we find in eukaryotic cells today, retaining some of their own DNA while losing much of it to the host cell's genome. This evolutionary process is supported by the presence of their own circular DNA and similarities to certain bacteria.
What else can I help you with?
What is the middle of the mitochondrion called?
mitochondrial matrix
Why is the mitochondrial DNA in the cells of offspring the same as the mitochondrial DNA in the offspring mother?
Mitochondrial DNA (mtDNA) is inherited exclusively from the mother because the mitochondria in the sperm are typically destroyed during fertilization. This means that all the mitochondria in the developing embryo come from the egg cell. As a result, the offspring's mtDNA is a direct maternal lineage, reflecting the genetic material passed down from the mother.
What do mitochondrial do?
F2f hhrrjrmrmt
What molecule crosses the mitochondrial membrane?
Adenosine triphosphate (ATP) crosses the mitochondrial membrane to provide energy for cellular processes.
Where does he Krebs cycle occur?
MITOCHONDRIA More specifically, the mitochondrial matrix.
When was Mitochondrial DNA - journal - created?
Mitochondrial DNA - journal - was created in 1980.
When was Mitochondrial Blues created?
Mitochondrial Blues was created on 2004-07-27.
Is mitochondrial DNA linear or circular in structure?
Mitochondrial DNA is circular in structure.
Is the mitochondrial membrane permeable to protons?
Yes, the mitochondrial membrane is permeable to protons.
Who shares your mitochondrial DNA?
Mitochondrial DNA comes from the mother, so the mother's maternal line and all her children share the same mitochondrial DNA.
What is the middle of the mitochondrion called?
mitochondrial matrix
Where do you get your mitochondrial DNA from?
In most organisms, including humans, the mitochondrial DNA is inherited from the mother.
Why is the mitochondrial DNA in the cells of offspring the same as the mitochondrial DNA in the offspring mother?
Mitochondrial DNA (mtDNA) is inherited exclusively from the mother because the mitochondria in the sperm are typically destroyed during fertilization. This means that all the mitochondria in the developing embryo come from the egg cell. As a result, the offspring's mtDNA is a direct maternal lineage, reflecting the genetic material passed down from the mother.
What has the author Roberto Scatena written?
Roberto Scatena has written: 'Advances in mitochondrial medicine' -- subject(s): Mitochondrial pathology, Mitochondrial Diseases, Effect of drugs on, Cells, Mitochondria, Physiology
Does mitochondrial DNA contain introns?
Yes, mitochondrial DNA does not contain introns. Mitochondrial DNA is a circular molecule that lacks introns, which are non-coding regions found in nuclear DNA.
What does mitochondrial DNA code for?
Mitochondrial DNA codes for certain proteins that are essential for the function of the mitochondria, the cell's powerhouse. It also contains genes involved in energy production through oxidative phosphorylation. Mitochondrial DNA is separate from the nuclear DNA and is passed down maternally.
Which is larger Human mitochondrial DNA or yeast mitochondrial DNA?
Yeast's is (~78kb), while human's is about 17kb
