| 설명 | 유전자는 길게 띠를 형성한 DNA분자의 일부분으로 한 가지 물질을 만드는데 필요한 모든 정보를 갖춘 기능적인 단위이다. 예를 들어 인슐린이라는 물질의 유전자라고 하면 사람의 세포내에 있는 긴 DNA 분자 중에서 인슐린이라는 물질을 만드는데 필요한 모든 정보를 가지고 있는 한 부분을 가리키는 말이다. 고전적인 생물학에서는 유전자가 표현형을 결정하거나 지정하는 염색체의 일부분이라고 정의되었지만, 오늘날에는 유전자에 대해서 분자적 정의가 제안되고 있으며 그 정의는 하나의 유전자는 하나의 효소를 결정 또는 암호화하는 유전물질의 일부분이라는 개념으로 이것이 이른바 1개의 유전자 1개 효소가설(one gene-one enzyme hypothesis)이다. 즉 1개의 유전자는 1개의 효소를 제작하는데 필요한 유전정보를 가진다는 것이다. 현재 이 가설이 받아들여지고 있다. |

| 설명 | 유전병을 치료할 목적으로, 정상적으로 기능하는 단일유전자 혹은 복수유전자를 어떤 기원에서 얻어내어 생세포에 도입하는 것. 유전물질은 유전자삽입 조작에 의해 수용세포에로 도입된다. 즉, 유전자를 끼워 넣은 새로운 세포를 사용하는 치료로서 1980년 미국의 학자가 지중해빈혈환자에게 강행하여 비판을 받았지만, 미국 국립보건연구소는 1990년 9월 아데노신 데아미나아제(adenosine deaminase, ADA) 결핍증 환자의 림프구에 ADA 유전자를 끼워 넣는 치료를 시작한 이래 현재는 암을 포함한 많은 질병들을 치료하는 목적으로 쓰인다. |

| lethal gene | A gene that produces a genotype that leads to death of the organism before reproduction is possible or that precludes reproduction; for a recessive gene the homozygous or hemizygous state is lethal. (05 Mar 2000) |
|---|
| y-suppressed lethal gene | <genetics> In the fruit fly Drosophila, this is a recessive, lethal gene that kills XO flies but not normal XY male flies. (09 Oct 1997) |
|---|---|
| zygotic lethal gene | <genetics> A mutated or otherwise defective gene at embryonic or larval stages. (06 May 1997) |
| balanced lethal system | <genetics> A population with non-linked, recessive alleles of a gene, where an individual who has two copies of the recessive allele and is therefore homozygous is dead, while an individual who has only one copy of it, and one copy of a different allele (and is heterozygous) survives. (09 Oct 1997) |
| genes, lethal | Genes which result in the premature death of the organism; dominant lethal genes kill heterozygotes, whereas recessive lethal genes kill only homozygotes. (12 Dec 1998) |
| genetic lethal | A disorder that prevents effective reproduction by those affected; e.g., Klinefelter syndrome. (05 Mar 2000) |
| granuloma, lethal midline | A non-neoplastic disease of unknown aetiology beginning with inflammation, ulceration, and perforation of nose and palate and progressing to gradual destruction of midline facial structures. (12 Dec 1998) |
| chicken embryo lethal orphan virus | <virology> A virus with characteristics of adenovirus, and similar to quail bronchitis virus. Synonym: chicken embryo lethal orphan virus. (05 Mar 2000) |
| minimal lethal dose | <pharmacology> The minimal dose of a toxic substance or infectious agent that is lethal, as assayed in various experimental animals (e.g., the least amount of diphtheria toxin that, on an average, kills a 250-g guinea pig within 96 hours after subcutaneous inoculation). When followed by a subscript (generally "MLD50"), denotes the minimal dose that is lethal to a certain percentage (e.g., 50%) of animals so assayed, LD05. See: lethal dose. (05 Mar 2000) |
| clinical lethal | A disorder that culminates in premature death. (05 Mar 2000) |
| conditional-lethal mutant | A viral mutant that can replicate under some (permissive) conditions but not under other (restrictive or nonpermissive) conditions, the parent (wild type) strain being able to replicate under both conditions. See: suppressor-sensitive mutant, temperature-sensitive mutant. Synonym: conditional-lethal mutant. (05 Mar 2000) |
| conditionally lethal mutant | A viral mutant that can replicate under some (permissive) conditions but not under other (restrictive or nonpermissive) conditions, the parent (wild type) strain being able to replicate under both conditions. See: suppressor-sensitive mutant, temperature-sensitive mutant. Synonym: conditional-lethal mutant. (05 Mar 2000) |
| dominant lethal trait | Trait, expressed in the phenotype if present in the genotype, that precludes having descendants. All such cases are necessarily sporadic and must represent new mutations as the usual methods of classical genetics provide no means of demonstrating any genetic component whatsoever, except for tenuous arguments such as advanced paternal age. Molecular biology may help although the methods may be tedious; if there is an epistatic gene that may mask the trait, the logic is more tractable, though complex. (05 Mar 2000) |
| lethal | Deadly, fatal. Origin: L. Lethalis, from lethum = death (18 Nov 1997) |
| lethal coefficient | <microbiology> That concentration of disinfectant that kills bacteria at 20-25캜 in the shortest period of time. (05 Mar 2000) |
| lethal dose | <pharmacology> The amount, or dosage, of a toxin necessary to cause death. (16 Mar 1998) |
