| 설명 | 핵 이외의 세포질 속에 있는 유전자 DNA. 주로 사립체, 색소체 따위의 세포 소기관에서 볼 수 있는 DNA와 플라스미드 DNA를 통틀어 이른다. 세균세포내에서 발견되는 염색체 이외의 자가복제 유전자 구조로서, 세포성장에 필수적이 아닌 여러 가지 기능의 유전자를 가지고 있다. 플라스미드는 숙주의 생존에 필수적인 것은 아니며, 세균염색체와 어느 정도를 관련을 가지며 독자적으로 복제하고, 다양한 형질을 숙주에 부가해, 딸세포에 전달한다. 플라스미드 상에는 복제에 관한 유전자 외에, 약제 내성인자(R인자), 창자관 독소생성, 성결정인자(F인자) 등의 유전자를 갖고 있는 것이 있다. 전달성 플라스미드는 다른 균과의 접합을 유발시켜 자신의 DNA를 전달할 수 있다. 근래 플라스미드는 그 특성을 이용해서 유전공학에 이용될 가능성이 있어서 크게 주목되고 있다. 세균 내의 플라스미드를 세포 밖으로 빼내고 제한효소로 고리를 끊은 뒤, 가령 사람의 인슐린을 만드는데 관여하는 DNA 조각을 이에 끼워 맞춰 다시 세균의 세포 내로 돌려보내 넣어주면 이종의 DNA 조각을 가진 잡종 플라스미드는 정상적으로 증식하고 세균이 분열할 때마다 인슐린을 생성하게 된다. |

| crown gall plasmid | A plasmid, or type of circular DNA, found in the bacteria Agrobacterium tumefaciens which infects dicot plants. Part of the plasmid inserts itself into the plant genome and causes tumours to form in the roots or in the stems nearest the roots. The plasmid has been used by geneticists, minus the tumour-causing parts, as a vector towards the genetic engineering of plants. (09 Oct 1997) |

| crown gall | Gall or tumour, found in many dicotyledonous plants, caused by the bacterium Agrobacterium tumefaciens. (18 Nov 1997) |
|---|---|
| crown gall tumour | A disease which afflicts dicot plants, caused by the bacteria Agrobacterium tumefaciens. The disease causes large tumours to form in the roots or in the stems nearest the roots, deforming the plant along its base (where it meets the ground). (09 Oct 1997) |
| gall | 1. To fret and wear away by friction; to hurt or break the skin of by rubbing; to chafe; to injure the surface of by attrition; as, a saddle galls the back of a horse; to gall a mast or a cable. "I am loth to gall a new-healed wound." (Shak) 2. To fret; to vex; as, to be galled by sarcasm. "They that are most galled with my folly, They most must laugh." (Shak) 3. To injure; to harass; to annoy; as, the troops were galled by the shot of the enemy. "In our wars against the French of old, we used to gall them with our longbows, at a greater distance than they could shoot their arrows." (Addison) Origin: OE. Gallen; cf. F. Galer to scratch, rub, gale scurf, scab, G. Galle a disease in horses' feet, an excrescence under the tongue of horses; of uncertain origin. Cf. Gall gallnut. A wound in the skin made by rubbing. 1. <physiology> The bitter, alkaline, viscid fluid found in the gall bladder, beneath the liver. It consists of the secretion of the liver, or bile, mixed with that of the mucous membrane of the gall bladder. 2. The gall bladder. 3. Anything extremely bitter; bitterness; rancor. "He hath . . . Compassed me with gall and travail." (Lam. Iii. 5) "Comedy diverted without gall." (Dryden) 4. Impudence; brazen assurance. <anatomy> Gall bladder, the membranous sac, in which the bile, or gall, is stored up, as secreted by the liver; the cholecystis. Gall duct, a duct which conveys bile, as the cystic duct, or the hepatic duct. Gall sickness, a remitting bilious fever in the Netherlands. <botany> Gall of the earth, an herbaceous composite plant with variously lobed and cleft leaves, usually the Prenanthes serpentaria. Origin: OE. Galle, gal, AS. Gealla; akin to D. Gal, OS. & OHG. Galla, Icel. Gall, SW. Galla, Dan. Galde, L. Fel, Gr, and prob. To E. Yellow. See Yellow, and cf. Choler. <zoology> An excrescence of any form produced on any part of a plant by insects or their larvae. They are most commonly caused by small Hymenoptera and Diptera which puncture the bark and lay their eggs in the wounds. The larvae live within the galls. Some galls are due to aphids, mites, etc. See Gallnut. The galls, or gallnuts, of commerce are produced by insects of the genus Cynips, chiefly on an oak (Quercus infectoria or Lusitanica) of Western Asia and Southern Europe. They contain much tannin, and are used in the manufacture of that article and for making ink and a black dye, as well as in medicine. <medicine> Gall insect See Gallfly. Origin: F. Galle, noix de galle, fr. L. Galla. Source: Websters Dictionary (01 Mar 1998) |
| gall duct | An obsolete term for bile duct. (05 Mar 2000) |
| Gall, Franz | <person> German-Austrian anatomist, 1758-1828. See: Gall's craniology. (05 Mar 2000) |
| Gall's craniology | 1. <study> The science of the special functions of the several parts of the brain, or of the supposed connection between the various faculties of the mind and particular organs in the brain. 2. In popular usage, the physiological hypothesis of Gall, that the mental faculties, and traits of character, are shown on the surface of the head or skull; craniology. Gall marked out on his model of the head the places of twenty-six organs, as round inclosures with vacant interspaces. Spurzheim and Combe divided the whole scalp into oblong and conterminous patches. Origin: Gr, the mind: cf. F. Phrenologie. Source: Websters Dictionary (01 Mar 1998) |
| cystic gall duct | The ductus leading from the gallbladder; it joins the hepatic duct to form the common bile duct. Synonym: ductus cysticus. (05 Mar 2000) |
| relaxed plasmid | A plasmid that replicatesindependently of the main bacterial chromosome and is present in 10-500 copies per cell. (09 Oct 1997) |
| RNA plasmid | <molecular biology> DsRNA found in yeasts, also called killer factors. Their nomenclature is uncertain and some scientists consider them viruses. (23 Aug 1998) |
| R plasmid | <molecular biology> A plasmid that confers resistance to one or more antibiotics or other poisonous compounds in a bacterium. (17 Dec 1997) |
| plasmid | <molecular biology> A small, independently replicating, piece of extrachromosomal cytoplasmic DNA that can be transferred from one organism to another. Linear or circular DNA molecules found in both pro and eukaryotes capable of autonomous replication. Stringent plasmids occur at low copy number in cells, relaxed plasmids at high copy number, ca 10 to 30. Plasmids can become incorporated into the genome of the host or can remain independent. An example is the f factor of E. Coli. May transfer genes and plasmids carrying antibiotic resistant genes can spread this trait rapidly through the population. Described largely from bacteria and protozoa. Some plasmids are capable of integrating into the host genome. A number of artificially constructed plasmids are used as cloning vectors. (14 Oct 1997) |
| conjugative plasmid | Self-transmissible plasmid, a plasmid which encodes all the functions needed for its own intercellular transmission by conjugation. (09 Oct 1997) |
| cryptic plasmid | A plasmid which has no apparent effect on the phenotype of its host cell and has no genes other than the ones needed for itself to replicate and spread to other cells. (09 Oct 1997) |
| hybrid plasmid | <molecular biology> A plasmid (circular DNA molecule) which is composed partly of the DNA of an organisms (or virus's) genome and partly of foreign DNA that has been inserted artificially. (09 Oct 1997) |
| stringent plasmid | <molecular biology> A plasmid that only replicates along with the main bacterial chromosome and is present as a single copy, or at most several copies, per cell. (16 Dec 1997) |
