| 설명 | 구조 유전자의 염기 배열 가운데 단백질 합성의 정보를 가진 부분. 최종적으로 mRNA로서 해독될 수 있는 DNA의 부분으로, 진핵생물의 유전 정보는 정보를 가지지 않은 염기의 배열에 의하여 DNA 가운데에서 mRNA에 대응하는 염기배열이 아미노산 배열을 규정하지 않는 인트론으로 분단되어 있는 경우가 많은데, 이 경우에 정보를 가지고 있는 부분을 이른다. 최종적으로 단백질로서 발현하는 유전자의 배열부분. 인트론과 대응되는 유전자 배열부분이다. 일반적으로 진핵생물의 유전자에서는 단백질로서 발현하는 유전자가 발현하지 않는 염기배열(인트론)에 의해 분단되어 존재한다. DNA를 전사한 mRNA(전령 RNA) 전구체에서 mRNA가 되는 단계에서 인트론이 분리되어 유전 정보를 가진 엑손 부분만이 연결되어 mRNA 가 완성되며 이것을 거푸집으로 삼아 단백질이 합성된다. 엑스-선(X-rays) 다양한 성질이 존재하며, 이로 인해 많은 의학적 이용이 가능하다. 1.사진판에 X-선이 닿으면, 까맣게 변하게 하는 성질이 있다. 2.X-선이 밀도가 서로 다른 물질을 통과하게 되면, 각기 통과하는 비율이 달라지므로, 필름에 서로 다른 명암을 표시하여 진단이 가능하도록 해준다. 3.실제로 X-선은 단순한 필름으로는 보이지 않으며, 특수 필름을 사용해야 한다. 4.직진하는 성질이 있다. 따라서 방사선치료에서 이를 이용하여 일정한 범위를 정할 수 있다. 5.주위로 방사능을 전하는 성질이 있다. 방사능은 인체에 유해하여, 심한 경우 암까지 발생시킬 수 있다. 따라서, X-선을 이용하여 촬영시, 방사능오염이 되지 않도록 검사자와, 피검사자 모두 주의를 해야 한다. 6. X-선은 다른 물체와 닿으면, 그 물질을 이온화 시키는 성질이 있다. |

| exon trapping vincent van buren | <molecular biology, technique> A technique used to identify vector. The vector has two exons that are normal, splicedtogether in a transcript.Fragments of DNA can be inserted into the intron, and when the insert is an exon, the exon is splicedinto the transcript, thereby giving a longer transcript that can be detected by Northern blotanalysis. (09 Oct 1997) |

| van Buren's disease | A disease of unknown cause in which there are plaques or strands of dense fibrous tissue surrounding the corpus cavernosum of the penis, causing deformity and painful erection; sometimes associated with Dupuytren's contracture. Synonym: penile fibromatosis, van Buren's disease. (05 Mar 2000) |
| van Buren sound | A standard sound, available in several calibers, with a gently curved tip designed to follow the contour of the deep bulbous urethra in the male; used for urethral calibration or dilation. (05 Mar 2000) |

| radiofrequency trapping | <radiobiology> Use of RF waves to pitch angle scatter particles flowing axially into a magnetic mirror cell. The particles are scattered out of the loss cone and are trapped. (See entries for pitch angle scattering, magnetic mirror, loss cone.) (09 Oct 1997) |
| spin trapping | A technique for detecting short-lived reactive free radicals in biological systems by providing a nitrone or nitrose compound for an addition reaction to occur which produces an electron spin resonance spectroscopy-detectable aminoxyl radical. In spin trapping, the compound trapping the radical is called the spin trap and the addition product of the radical is identified as the spin adduct. (free rad res comm 1990;9(3-6):163) (12 Dec 1998) |
| entropy trapping | <radiobiology> The process of trapping an ordered beam of particles in a magnetic field configuration (for example, cusp geometry) by randomising the ordered motion of the particles, with corresponding increase in the entropy of the system. (09 Oct 1997) |
| exon | <molecular biology> The sequences of the primary RNA transcript (or the DNA that encodes them) that exit the nucleus as part of a messenger RNA molecule. In the primary transcript neighbouring exons are separated by introns. (18 Nov 1997) |
| exon shuffle | The variation in the patterns by which RNA may produce diverse sets of exons from a single gene. (05 Mar 2000) |
| exon shuffling | <molecular biology> Process by which the evolution of proteins with multifunctional domains could be accelerated. If exons each encoded individual functional domains, then introns would allow their recombination to form new functional proteins with minimal risk of damage to the sequences encoding the functional parts. (18 Nov 1997) |

| Vincent's angina | An ulcerative infection of the oral soft tissues including the tonsils and pharynx caused by fusiform and spirochetal organisms; it is usually associated with necrotizing ulcerative gingivitis and may progress to noma. Death from suffocation or sepsis may occur. (05 Mar 2000) |
| Vincent's bacillus | Probably Fusobacterium nucleatum. (05 Mar 2000) |
| Vincent's disease | <disease> An acute or recurrent form of gingivitis of young to middle-aged adults characterised by red and painful gums, fetid breath and gum destruction. Other features may include fever and enlargement of the regional lymph nodes. Pathogenesis of this condition is thought to be secondary to a fusiform bacillus and spirochetal (Treponema vincentii) microorganisms. (14 Oct 1997) |
