| 영문 | ovulation cycle | 한글 | 배란주기 |
|---|---|---|---|
| 설명 | 사춘기가 되어 난소가 뇌하수체전엽으로부터의 생식샘자극호르몬의 작용을 받아 원시난포가 발육하고 성숙난포가 된다. 결국에는 난포벽이 파열되어 과립막세포로 둘러싸인 난자가 복강내로 배출된다(배란). 배란 후 24~96시간으로 과립막세포가 비대증식해서 황체를 형성한다. 수정되지 않은 경우 월경황체는 약 10일간 존속하고 퇴행변성해서 백체가 된다. 황체가 퇴행변성하면 다음의 난포가 성숙한다. 난소에서는 이 주기가 반복되고 있다. |

| 영문 | white blood cell(WBC), leukocyte | 한글 | 백혈구 |
|---|---|---|---|
| 설명 | 혈액내에 골수구계세포와 림프계세포, 단핵구계세포를 모두 통틀어 말한다. 백혈구의 증가가 있으면 대개 감염이 있거나, 혹은 탈수현상이 있음을 의미한다. 또한 지나친 백혈구수의 감소는 인체내 면역기능이 떨어져 있음을 의미하며, 다른 질병에 의해 나타나는 이차적인 현상이 아닌지 꼭 진단을 받아보아야 한다. |

| 영문 | mast cell | 한글 | 비만 세포 |
|---|---|---|---|
| 설명 | 동물의 결합 조직 가운데 널리 분포하는 세포. 결합조직과 점막조직 내에 있는 호염기성 색소로 이염색성(metachromasia)을 나타내는 과립을 가진 방추형의 세포에 작은 둥근 핵을 가진다. 비만세포의 표면에는 IgE에 대한 수용체가 존재하며, 수용체에 결합한 IgE 분자들끼리 다가의 항원에 의해 서로 연결되면 비만세포 과립탈출 반응이 일어나, 히스타민, 세로토닌, 헤파린 등의 화학전달 물질이 방출되어, 즉시형 알레르기 반응 등의 증상을 일으킨다. 피부, 장막, 혈관 주위, 점막 주변에 있다. |

| cell cycle restriction point | <cell biology, molecular biology> A point, late in G1, after which the cell must, normally, proceed through to division at its standard rate. (26 Mar 1998) |
|---|
| cell cycle | <cell biology, molecular biology> The sequence of events between mitotic divisions. The cycle is conventionally divided into G0, G1, (G standing for gap), S (synthesis phase during which the DNA is replicated), G2 and M (mitosis). Cells that will not divide again are considered to be in G0 and the transition from G0 to G1 is thought to commit the cell to completing the cycle and dividing. (26 Mar 1998) |
|---|---|
| cell cycle proteins | Proteins that control the cell division cycle. This family of proteins includes a wide variety of classes, including cyclin-dependent kinases, mitogen-activated kinases, cyclins, and phosphoprotein phosphatases (phosphoprotein phosphatase) as well as their putative substrates such as chromatin-associated proteins, cytoskeletal proteins, and transcription factors. (12 Dec 1998) |
| cell division cycle gene | Genes which control the yeast cell cycle. There are around 50 different genes which do this. (09 Oct 1997) |
| cell division cycle mutant | A yeast cell which has cell division cycle genes that have mutated to become sensitive to temperature, at certain temperatures (usually high ones), various parts of the normal yeast cell cycle become abnormal, and in some strains the yeast cell does not survive at all. (09 Oct 1997) |
| restriction | 1. The process with which foreign DNA that has been introduced into a prokaryotic cell becomes ineffective. 2. A limitation. (05 Mar 2000) |
| restriction endonuclease | <enzyme, molecular biology> Class of bacterial enzymes that cut DNA at specific sites. In bacteria their function is to destroy foreign DNA, such as that of bacteriophages (host DNA is specifically modified at these sites). Type I restriction endonucleases occur as a complex with the methylase and a polypeptide that binds to the recognition site on DNA. They are often not very specific and cut at a remote site. Type II restriction endonucleases are the classic experimental tools. They have very specific recognition and cutting sites. The recognition sites are short, 4-8 nucleotides and are usually palindromic sequences. Because both strands have the same sequence running in opposite directions the enzymes make double stranded breaks, which, if the site of cleavage is off centre, generates fragments with short single stranded tails, these can hybridise to the tails of other fragments and are called sticky ends. They are generally named according to the bacterium from which they were isolated (first letter of genus name and the first two letters of the specific name). The bacterial strain is identified next and multiple enzymes are given Roman numerals. For example the two enzymes isolated from the R strain of E. Coli are designated Eco RI and Eco RII.

| restriction enzyme cutting site | <molecular biology> A specific nucleotide sequence of DNA at which a particular restriction enzyme cuts the DNA. Some sites occur frequently in DNA (for example, every several hundred basepairs), others much less frequently (rare-cutter, for example, every 10,000 base pairs). (10 Mar 1998) |
| restriction enzyme, endonuclease | A protein that recognises specific, short nucleotide sequences and cuts DNA at those sites. Bacteria contain over 400 such enzymes that recognise and cut over 100 different DNA sequences. See restriction enzyme cutting site. (05 Mar 2000) |
| restriction fragment | <molecular biology> The fragments of DNA generated by digesting DNA with a specific restriction endonuclease. Each of the fragments ends in a site recognised by that specific enzyme. (10 Mar 1998) |
| restriction fragment length polymorphism | <molecular biology, technique> A method that allows familial relationships to be established by comparing the characteristic polymorphic patterns that are obtained when certain regions of genomic DNA are amplified (typically by PCR) and cut with certain restriction enzymes. The variation in the length of DNA fragments produced by a restriction endonuclease that cuts at a polymorphic locus. Such variations are generated by mutations that create or abolish recognition sites for these enzymes. This is a key tool in DNA fingerprinting, reflecting the existence of different alleles in the individual. Restriction fragment length polymorphism mapping is also used in plant breeding to see if a key trait such as disease resistance is inherited. In principle, an individual can be identified unambiquously by restriction fragment length polymorphism hence the use of restriction fragment length polymorphism in forensic analysis of blood, hair or semen). Similarly, if a polymorphism can be identified close to the locus of a genetic defect, it provides a valuable marker for tracing the inheritance of the defect. Synonym: DNA fingerprinting. Acronym: RFLP (12 Jan 1998) |
| restriction length polymorphism | Fragment length polymorphism, the existence of allelic forms recognizable by the length of fragments that result when the nucleotide chain is treated by a specific restriction enzyme that cleaves wherever a particular sequence of nucleotides occurs. A mutation in this sequence changes cleaving and hence the number of fragments. (05 Mar 2000) |
| restriction map | <molecular biology> Map of DNA showing the position of sites recognised and cut by various restriction endonucleases. (12 Jan 1998) |
| restriction mapping | Use of restriction endonucleases to analyze and generate a physical map of genomes or genes. The nucleotide sequence determined is often then translated into an amino acid sequence, providing a means for sequencing the protein for which the gene codes, or for which the mRNA is a messenger. (12 Dec 1998) |
| restriction methylation | The enzymatic addition of methyl groups to selected adenine and cytosine residues to protect from hydrolysis by certain restriction enzymes. (05 Mar 2000) |
