| 설명 | 혈액이나 소변에서 실시하는 검사항목. pH검사는 인체의 체액의 산성, 알칼리성을 알아보는 중요한 검사이다. 인체는 약알칼리성에 속하나, 이보다 pH의 증가나 감소가 나타날 경우, 생명에 위험이 발생한다. 인체내에는 이런 산도의 증감을 막기위해, 이른바 완충제들이 많이 존재하며, 특히 허파와 콩팥이 완충작용을 수행하는 주요기관이다. 콩팥은 산도가 높을 경우, 소변에서 산도를 증가시켜 배출함으로써 혈액내의 알칼리성 농도가 증가하도록 한다. 또한 허파에서도, 혈액내에 산도가 증가시 호흡을 증가함으로써 밖으로 산의 배출을 증가시킨다. 이런 허파와 콩팥의 균형은 아주 적절히 이루어지고 있으며, 어느 한 기관의 이상이 발생하면, 이런 균형은 깨어지기 쉽다. |

| genetic recombination | <molecular biology> Formation of new combinations of alleles in offspring (viruses, cells or organisms) as a result of exchange of DNA sequences between molecules. It occurs naturally, as in crossing over between homologous chromosomes in meiosis or experimentally, as a result of genetic engineering techniques. (18 Nov 1997) |

| recombination | <molecular biology> The creation, by a process of intermolecular exchange, of chromosomes combining genetic information from different sources, typically two genomes of a given species. Site specific, homologous, transpositional and nonhomologous illegitimate) types of recombination are known. 1st ed (18 Nov 1997) |
| recombination coefficient | <radiobiology> The rate of recombination of positive ions with electrons (or negative ions) in a gas, per unit volume, divided by the product of the particle densities of the two species (positive ions and electrons/negative ions) involved. (09 Oct 1997) |
| recombination fraction | The proportion of progeny of a mating pair of specific genotype and coupling phase that are recombinant; there must be no differential selection among the possible types of progeny, and the recombination fraction should be the same regardless of the alleles involved or their coupling phase. (05 Mar 2000) |
| recombination frequency | The frequency at which crossingover occurs between two chromosomal loci--the probability that twoloci will become unlinked during meiosis. (09 Oct 1997) |
| recombination, genetic | Production of new arrangements of genes by various mechanisms such as assortment and segregation, crossing over, gene conversion, transformation, conjugation, transduction, f-duction, or mixed infection of viruses. (12 Dec 1998) |
| recombination nodule | <molecular biology> Protein containing assemblies of about 90 nm diameter placed at intervals in the synaptonemal complexes that develop between homologous chromosomes at the zygotene stage of meiosis. Some nodules may be associated with the site of recombination. (18 Nov 1997) |
| recombination radiation | <physics> Radiation produced when a free electron in a plasma is captured by an ion. (09 Oct 1997) |
| mitotic recombination | <genetics, molecular biology> Somatic crossing over. Crossing over can occur between homologous chromosomes during mitosis, but is very rare because the chromosomes do not normally pair. When it occurs it can lead to new combinations of previously linked genes. Although infrequent, mitotic recombination has been utilised for genetic analysis in Aspergillus and in studies on developmental compartments in Drosophila where the frequency of mitotic recombination can be increased by X irradiation. (18 Nov 1997) |
| high frequency recombination strain | A type of bacterial strain which is able to pass on genetic information to neighboring bacteria at a high rate. The high-frequency recombination strain (Hfr) is able to do this because it possesses the f plasmid and can therefore initiate bacterial conjugation. (09 Oct 1997) |
| homologous recombination | <molecular biology> Genetic recombination involving exchange of homologous loci. Important technique in the generation of null alleles (knockouts) in transgenic mice. (18 Nov 1997) |
| site-specific recombination | <molecular biology> A type of recombination that occurs between two specific short DNA sequences present in the same or in different molecules. An example is the integration and excision of _ prophage. (18 Nov 1997) |
| somatic recombination | One of the mechanisms used to generate diversity in antibody production is to rearrange the DNA in B-cells during their differentiation, a process that involves cutting and splicing the immunoglobulin genes. Somatic recombination via homologous crossing over occurs at a low frequency in Aspergillus, Drosphilia and Saccharomyces and in mammalian cells in culture. It may be detected through the production of homozygous patches or sectors after mitosis of cells heterozygous for suitable marker genes. (18 Nov 1997) |
| dissociative recombination | <radiobiology> The combination of an electron with a positive molecular ion, followed by dissociation of the molecule in which the resulting atoms/molecules carry off the excess energy released in the recombination. (09 Oct 1997) |
| Alfven ion cyclotron instability | <radiobiology> An electromagnetic microinstability near the ion cyclotron frequency, driven by the ion loss cone in a mirror device. Acronym: AIC (13 Nov 1997) |
