The circular, double stranded genome of eukaryotic mitochondria.
The DNA of the mitochondrial genome.
DNA found in the mitochondria of a cell. Mitochondria are about the size of bacteria and are scattered throughout a cell outside its nucleus. Since there are between 500 to 1,000 mitochondria in every cell, as opposed to one nucleus, mitochondrial DNA analysis affords a better chance of a DNA profile than nuclear DNA analysis in cases where a sample is decayed or degraded, such as skeletal remains that have been exposed to the elements for years.
DNA which is not located in the nucleus of the cell but in the mitochondria. Because mitochondrial DNA is inherited only from the mother, it provides an unaltered link to past generations.
an independent DNA genome, usually circular, that is located in the mitochondrion
a single double stranded circular molecule
DNA found in mitochondria, energy-generating structures found in plant and animal cells, which contain a few genes. Mitochondrial genes are always maternally inherited, since sperm contribute no mitochondria to the fertilized egg.
DNA found in mitochon-dria. Abbreviated mtDNA. Some human diseases have been traced to defects in mtDNA.
DNA found in the mitochondria (an organelle in cells that generates energy), and passed into offspring through the maternal line.
Mitochondria, and chloroplasts in plants, carry their own small chromosomes, usually in multiple copies per organelle. These carry a limited number of genes which code for rRNA, tRNA and a few organelle proteins. This DNA is maternally inherited.
The genetic material of the mitochondria - the organelle that generates energy for the cell. The DNA in mitochondria is different from that in the nucleus. Many scientists believe that this DNA is the remnant of a bacterium that invaded the cell in very early evolution. Mitochondrial DNA (mtDNA) is typically passed on only from the mother during sexual reproduction as it is only the nucleus of the sperm that enters the egg upon fertilisation. This means there is little change in the mtDNA from generation to generation.
is DNA separate from that on chromosomes and is contained within the mitochondria. Mitochondrial DNA is is only inherited through the mother. Since multiple mitochondria are present in a cell, multiple copies of mitochondrial DNA are also present.
The genetic material found in the mitochondria, which is different from the cell's DNA in the nucleus. Mitochondria are passed on from one generation to the next in the cytoplasm of the egg, so they are inherited from the mother.
The DNA genome contained within mitochondria and encoding a small subset of mitochondrial functions; mtDNA is typically circular and 15_20 kilobases in size, containing little noncoding information between genes.
Usually abbreviated to mtDNA. A circular strand of DNA and associated proteins in the mitochondrion (singular of mitochondria) that carries the genes and functions in the transmission of hereditary information.
Abbreviated mtDNA (pronounced em-tee-D-N-A). A type of DNA that is found in small bodies within cells called mitochondria. Both women and men have mtDNA, but only mothers pass on their mtDNA to the next generation.
The genetic material found in mitochondria. It is passed down from females to both sons and daughters, but sons do not pass down their mother's mtDNA to their children.
The mitochondrial genome consists of a circular DNA molecule, with 5 to 10 copies per organelle.
The genetic material of the mitochondria, the organelles that generate energy for the cell. Mitochondrial DNA is passed down from the mother to all her children, both sons and daughters so it is identical to the mother's.
The DNA found in the many mitochondria found in each cell of a body. The sequencing of mitochondrial DNA can link individuals descended from a common female ancestor.
Double-stranded DNA contained within mitochondria that encodes mitochondrial tRNAs, rRNAs, and proteins. Several copies of the mitochondrial genome are found in each organelle.
The genetic material found in mitochondria, the organelles that generate energy for the cell. Not inherited in the same fashion as nucleic DNA. See also: cell, DNA, genome, nucleus
DNA found in the mitochondria of a cell, the mitochondrial chromosome comes from the egg so it is inherited only from the mother.
DNA found in the cellular organelles called mitochondria; identical to mother's mitochondrial DNA
The DNA found in the mitochondria of cells. It produced energy for the cell, and contains many enzymes important for cell metabolism, including those responsible for the conversion of food to usable energy. The DNA contained within the mitochondria is maternally inherited, whereas the DNA found in the nucleus of the cell is inherited from both parents.
the DNA found only in the mitochondria (the powerhouses of the cell) and inherited only from the mother.
A short sequence found outside of the cell nucleus in cells. Called mitochondria, this material is used in the absence of quality genetic material like blood, semen or saliva. It is passed only from mother to child; siblings share maternal mitochondria. Hairs and fingernails are good sources of mitochondria.
The numerous, small, circular genetic material of mitochondria--the organelles that generate energy for the cell. Not to be confused with nuclear DNA, mitochondrial DNA is inherited only from the mother.
The DNA in the mitochondria of eukaryotes. This DNA codes for many of the organelles functions and is replicated indepently of the nuclear DNA. Mitochondrial DNA (mtDNA) appears to contain no introns.
genetic material found in mitochondria that is used to show genetic relatedness
Genetic material inside the mitochondria. Essentially all the mitochondria of an individual come from the cytoplasm of the egg, so all mitochondrial DNA is inherited through the maternal line.
a relatively new method of DNA analysis that examines the DNA in mitochondria, which are small organelles responsible for producing the energy in cells. Mitochondrial DNA techniques are not as discriminating as traditional methods, but because mitochondria are resistant to degradation, it can be very useful in identifying badly burnt or decomposed samples.
genetic instructions inherited through the maternal line
Genetic material passed on from mothers to all their children, but only daughters are able to passit on. Useful to genealogists for learning about their maternal roots.
The genetic material of the mitochondria, the organelles that generate energy for the cell. [ Talking Glossary
Mitochondrial DNA (mtDNA) is DNA that is located in mitochondria. This is in contrast to most DNA of eukaryotic organisms, which is found in the nucleus. Nuclear and mtDNA are thought to be of separate evolutionary origin, with the mtDNA being derived from bacteria that were engulfed by early precursors of eukaryotic cells.
