| 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. |

| composite | A colloquial term for resin materials used in restorative dentistry. Origin: L. Compositus, put together, fr. Compono, to put together (05 Mar 2000) |
| composite dental cement | An organic dental cement modified by the inclusion of inorganic materials treated with a coupling agent to bond them to the polymers. (05 Mar 2000) |
| composite graft | A graft composed of several structures, such as skin and cartilage or a full-thickness segment of the ear. (05 Mar 2000) |
| composite joint | A joint composed of three or more skeletal elements, or in which two anatomically separate joints function as a unit. For example, the telonavicular and calcaneocuboid joints act together as the compound transverse tarsal joint. Synonym: articulatio complexa, articulatio composita, composite joint, compound articulation. (05 Mar 2000) |
| composite resin | A synthetic resin usually acrylic based, to which a glass or natural silica filter has been added. Used mainly in dental restorative procedures. Origin: L. Compositus, put together, fr. Compono, to put together (05 Mar 2000) |
| composite resins | Synthetic resins, usually acrylic based, to which a high percentage (usually about 75% to 80%) of an inert filler has been added. Glass beads or rods, borosilicate glass powder, and natural silica are the most commonly used fillers. Filler particles are coated with a coupling agent that binds the particles to the resin matrix. They are used chiefly in dental restorative procedures. (12 Dec 1998) |
| composite transposon | <molecular biology> A segment of DNA which contains the insertion elements at either end but can contain just about anything in the middle (genes, markers, etc.). These types of transposons tend to be very large, and many of them came about when the inner two insertion elements of two smaller transposons stopped working and only the two at the far ends continue to work, so that when the transposon moves, it takes everything in between the two original transposons with it. Some composite transposons are used in genetics experiments, Tn5 and Tn10 are two such composite transposons which have genes that encode resistance to certain antibiotics. (05 Jan 1998) |
| direct composite resin restoration | A direct restoration made by inserting a plastic mix of auto or light-polymerised resins in a cavity prepared in a tooth. Synonym: direct composite resin restoration. (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) |
| 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) |
