| 설명 | 암수의 성을 결정하는 데 중요한 구실을 하는 염색체. 이것에 대하여 보통의 염색체를 보통염색체라고 한다. 암수의 구별이 있는 생물에서는 암수에 따라 다른 형과 수를 나타내는 염색체이며, 보통염색체에 비해 염색성이나 행동에서 차이가 있다. 특히 동물의 성염색체는 그런 경향이 강하다. 휴지기 및 핵분열 전기에 뚜렷한 이상응축을 나타내며 감수분열 때는 다른 염색체보다 먼저 앞서거나 끌려가는 행동을 보여준다. |

|---|---|---|---|
| 설명 | 유전정보를 담고 있는 DNA가 모여서 이루는 구조물로 핵속에 위치한다. 세포가 분열할 때 이것을 더욱 뚜렷이 관찰할 수가 있다. 이것은 사람처럼 고등생물체에서 너무나 많은 정보를 담고 있어, 엄청난 길이(사람에 있어서 전 DNA를 길이로 따지면 약 2m가 된다)가 된 DNA를 작은 핵이란 공간속에 보관하기 위해서 만들어진 구조이다. 이 염색체의 수는 생물의 종에 따라 다르며 사람의 경우는 46개이다. |

| 설명 | 염색체의 수나 구조의 이상. 이상이 생긴 세포나 개체는 유전적인 이상을 일으켜 사람의 경우, 다운 증후군-터너 증후군 따위의 여러 가지 형태로 나타난다. |

| mitochondrial chromosome | The DNA component of mitochondria, the chief function of which is synthesis of adenosine triphosphate and the management of cellular energy; the chromosome contains some 16,000 base pairs arranged in a circle. The inheritance is matrilineal, and the mutation rate is unusually high; since each cell contains thousands of copies a mutant form may assume an almost continuous gradation as in a galtonian process. Most of the mutations known have their impact on the respiratory chain. (05 Mar 2000) |

| anti-mitochondrial antibodies | A special serologic test that measures the level of antibodies to a particular portion of a cell (mitochondria). (27 Sep 1997) |
|---|---|
| bovine mitochondrial endonuclease | <enzyme> Dimer of 29kda peptide; prefers a conserved sequence in the displacement loop region of mitochondrial DNA; nicks double-stranded DNA and fragments single-stranded DNA Registry number: EC 3.1.21.- (26 Jun 1999) |
| genome, mitochondrial | The genetic information contained in the circular chromosome of the mitochondrion, a structure located outside the nucleus in the cytoplasm of the cell. The mitochondrial genome and the chromosomal (nuclear) genome together constitute the entire genome. (12 Dec 1998) |
| mitochondrial | Referring to mitochondria. (12 Dec 1998) |
| mitochondrial disease | <disease, neurology> An illnesse, frequently neurological, which can be ascribed to defects in mitochondrial function. If the defect is in the mitochondrial rather than the nuclear genome unusual patterns of inheritance can be observed. (18 Nov 1997) |
| mitochondrial encephalomyopathies | Brain diseases associated with disease of the muscles, accompanied by morphological changes in the muscle mitochondria and their metabolism. The mitochondrial encephalopathies are often multisystemic and vary considerably in age at onset, distribution of weakness, severity, and course. Mitochondrial cytochrome c oxidase deficiency appears to be implicated and often several mitochondrial enzymes are affected in the same patient. The brain lesions can be said to be clinical and morphological expressions of a mitochondrial defect. (12 Dec 1998) |
| mitochondrial gene | A functioning gene located not in the nucleus of a cell but in the mitochondrial chromosome. (05 Mar 2000) |
| mitochondrial genome | All of the DNA in the mitochondrial chromosome. (12 Dec 1998) |
| mitochondrial inheritance | The inheritance of a trait encoded in the mitochondrial genome. Because of the oddities of mitochondria, mitochondrial inheritance does not obey the classic rules of genetics. Persons with a mitochondrial disease may be male or female but they are always related in the maternal line and no male with the disease can transmit it to his children. (12 Dec 1998) |
| mitochondrial intermediate peptidase | <enzyme> Removes the octapeptide from the amino terminus of the intermediate protein processed from the protein precursor of certain mitochondrial proteins by the mitochondrial processing peptidase; smip from schizophyllum commune; rmip from rat; ymip from saccharomyces cerevisiae Registry number: EC 3.4.24.59 Synonym: mip peptidase, smip peptidase, rmip peptidase, ymip peptidase (26 Jun 1999) |
| mitochondrial matrix | The substance occupying the space enclosed by the inner membrane of a mitochondrion; it contains enzymes, filaments of DNA, ribosomes, granules, and inclusions of protein crystals, glycogen, and lipid. Synonym: mitochondrial matrix. (05 Mar 2000) |
| mitochondrial membrane | The double biomembrane surrounding the mitochondrion. (05 Mar 2000) |
| mitochondrial myopathies | Diseases of the muscles characterised by morphologic changes in mitochondria and often associated with excessive lipid accumulation. Muscle biopsies reveal "the presence of overly abundant and large mitochondria (often containing abnormal inclusions and cristae) in many muscle fibres. The terms mitochondrial and lipid storage have been used interchangeably to designate these myopathies, since the enzymes essential for intramuscular lipid metabolism are contained in the mitochondria, and a defect in the latter results in an abnormal accumulation of lipid bodies in muscle fibres." often defects in various oxidative enzymes figure. One type of mitochondrial myopathy is called pleoconial with reference to "a remarkably large number (pleo-) of enlarged mitochondria in the biopsied muscle", another is "called megaconial with reference to giant (mega-) mitochondria in the muscle." (adams and victor: principles of neurology, 2d ed, p980-1) (12 Dec 1998) |
| mitochondrial oxidative damage endonuclease | <enzyme> An 8-oxog-specific DNA endonuclease from rat liver mitochondria; recognises and incises at 8-oxog and abasic acid sites in duplex DNA Registry number: EC 3.1.25.- Synonym: oxidative damage-specific endonuclease, mtode enzyme (26 Jun 1999) |
| mitochondrial sheath | The spirally arranged mitochondria in the middle piece of a spermatozoon; may control movement of the tail. (05 Mar 2000) |

a circular DNA duplex found in the mitochondria. [Source: Agricultural Genome Information System, USDA]
