|---|---|---|---|
| 설명 | 암수의 성을 결정하는 데 중요한 구실을 하는 염색체. 이것에 대하여 보통의 염색체를 보통염색체라고 한다. 암수의 구별이 있는 생물에서는 암수에 따라 다른 형과 수를 나타내는 염색체이며, 보통염색체에 비해 염색성이나 행동에서 차이가 있다. 특히 동물의 성염색체는 그런 경향이 강하다. 휴지기 및 핵분열 전기에 뚜렷한 이상응축을 나타내며 감수분열 때는 다른 염색체보다 먼저 앞서거나 끌려가는 행동을 보여준다. |

|---|---|---|---|
| 설명 | 유전정보를 담고 있는 DNA가 모여서 이루는 구조물로 핵속에 위치한다. 세포가 분열할 때 이것을 더욱 뚜렷이 관찰할 수가 있다. 이것은 사람처럼 고등생물체에서 너무나 많은 정보를 담고 있어, 엄청난 길이(사람에 있어서 전 DNA를 길이로 따지면 약 2m가 된다)가 된 DNA를 작은 핵이란 공간속에 보관하기 위해서 만들어진 구조이다. 이 염색체의 수는 생물의 종에 따라 다르며 사람의 경우는 46개이다. |

| balanced chromosome | <genetics> A chromosome which is unable to pair with its homologue and participate in homologus recombination during meiosis because it contains several inversion mutations (that is, has segments which have become flip-flopped). (09 Oct 1997) |
|---|
| balanced anaesthesia | A technique of general anaesthesia based on the concept that administration of a mixture of small amounts of several neuronal depressants summates the advantages, but not the disadvantages of, the individual components of the mixture. (05 Mar 2000) |

| balanced articulation | The simultaneous contacting of the upper and lower teeth on the right and left and in the anterior and posterior occlusal areas in centric and eccentric positions within the functional range; used primarily in reference to the mouth, but also arranged and observed on articulators, developed to prevent a tipping or rotating of the denture bases in relation to the supporting structures. Synonym: balanced articulation, balanced bite. (05 Mar 2000) |
| balanced bite | The simultaneous contacting of the upper and lower teeth on the right and left and in the anterior and posterior occlusal areas in centric and eccentric positions within the functional range; used primarily in reference to the mouth, but also arranged and observed on articulators, developed to prevent a tipping or rotating of the denture bases in relation to the supporting structures. Synonym: balanced articulation, balanced bite. (05 Mar 2000) |
| balanced diet | A diet containing the essential nutrients with a reasonable ration of all the major food groups. (05 Mar 2000) |
| 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) |
| balanced occlusion | The simultaneous contacting of the upper and lower teeth on the right and left and in the anterior and posterior occlusal areas in centric and eccentric positions within the functional range; used primarily in reference to the mouth, but also arranged and observed on articulators, developed to prevent a tipping or rotating of the denture bases in relation to the supporting structures. Synonym: balanced articulation, balanced bite. (05 Mar 2000) |
| balanced polymorphism | <genetics> A type of polymorphism where the many morphs are alleles. The polymorphism is maintained in a population rather than the norm of one allele eventually becoming the only allele in the population, because individuals who are heterozygous, or have two different alleles, are more adaptive (more fit) than individuals who are homozygous, or have two copies of the same allele. (09 Oct 1997) |
| balanced stock | <genetics> A genetic strain of any of several lab organisms (like fruit flies) which can be maintained as heterozygous individuals without requiring constant artificial selection for the heterozygotes, due to a number of lethal recessive genes with the result that the homozygous females are sterile (unable to produce offspring) and the males with the wrong recessive alleles are dead. (Male fruit flies are not homozygous or heterozygous because they only have one allele per particular genetic loci in question). (09 Oct 1997) |
| balanced translocation | <genetics> A number of the chromosomal mutations called translocations, where a segment of DNA abnormally becomes attached to the wrong chromosome, which results in two nonhomologous chromosomes being able to cross over, something which normally can occur only between homologous chromosomes. (09 Oct 1997) |
| mechanically balanced occlusion | A balanced occlusion without reference to physiologic considerations, as on an articulator. (05 Mar 2000) |
| physiologically balanced occlusion | A balanced occlusion that is in harmony with the temporomandibular joints and the neuromuscular system. (05 Mar 2000) |
| dental occlusion, balanced | Dental occlusion in which the occlusal contact of the teeth on the working side of the jaw is accompanied by the harmonious contact of the teeth on the opposite (balancing) side. (12 Dec 1998) |
| accessory chromosome | A chromosome existing without its normal homologous chromosome; at the reduction division of gametogenesis an accessory chromosome is likely to be included in one daughter cell and not in the other, but may be lost completely by lagging behind on the equatorial plate. Synonym: monosome, odd chromosome, unpaired allosome, unpaired chromosome. (05 Mar 2000) |
| acentric chromosome | A fragment of a chromosome lacking a centromere and unable to attach to the mitotic spindle, therefore unable to take part in the division of a nucleus and randomly distributed in daughter cells. Synonym: acentric fragment. (05 Mar 2000) |
| acrocentric chromosome | A chromosome with the centromere placed very close to one end so that the short arm is very small, often with a satellite. (05 Mar 2000) |
