|---|---|---|---|
| 설명 | 세포의 dna 자체의 변이에 의해 일어나는 세포변이를 말한다. 이러한 경우 돌연변이로 일어난 세포는 그 이후 딸세포(daughter cell)에서도 그 변이가 여전히 유지되므로 종(species)의 변화나, 혹은 세포의 악성변환(malignant transformation)에 관여한다. |

| 설명 | 대립형질 중 잡종 제1대에서 숨어서 나타나지 않는 형질. 우성에 대응되는 말이다. 나타나는 쪽에 대해 열성이라 하고, 그 형질을 열성형질이라고 한다. 제2대(F2)에서는 열성형질은 분리되어 1/3의 비율로 나타난다. 유전적 대립형질에는 우성과 열성이 있고, 이것들은 우성유전자와 열성유전자에 의해 지배된다. 예를 들면, 어떤 우성형질을 지배하는 유전자를 A라 하고, 그것에 대응하는 열성유전자를 a라고 하면, 우성유전자를 가진 어버이(AA)와 열성유전자를 가진 어버이(aa)의 교배에 의하여 생긴 잡종 제1대(F1)는 Aa가 되어 우성형질을 나타낸다. Aa 유전자를 가진 F1끼리를 교배하면 잡종 제2대(F2)에서는 AA:Aa:aa가 1:2:1의 비율로 분리되어 열성형질은 F2대에 1/3의 비율로 생긴다. 우성-열성이란 형질의 가치 우열을 말하는 것이 아니다. 열성이 뒤떨어졌다는 인상을 준다고 하여 열성을 잠성으로, 우성을 현성으로 하자고 주장하는 학자도 있다. |

| autosomal recessive | <genetics> Mutation carried on an autosome that is deleterious only in homozygotes. (02 Jan 1998) |
|---|---|
| genes, recessive | Genes that are reflected in the phenotype only in the homozygous state. (12 Dec 1998) |
| recessive | <genetics> An allele or mutation that is only expressed phenotypically when it is present in the homozygous form. In the heterozygote it is obscured by dominant alleles. (18 Nov 1997) |
| recessive, autosomal | A gene on a nonsex chromosome (an autosome) that expresses itself only when there is no different gene present at that locus (spot on the chromosome). For example, cystic fibrosis (cf) is an autosomal recessive disorder. A cf child has the cf gene on both chromosome 7's (and so is said to be homozygous for cf). (12 Dec 1998) |
| recessive character | An inherited character determined by an allele in homozygous state only. See: dominance of traits. (05 Mar 2000) |
| recessive gene | A gene that is expressed onlywhen it is present in two copies or if theother copy is missing. (09 Oct 1997) |
| recessive inheritance | dominance of traits |
| recessive oncogene | <molecular biology> A single copy of this gene issufficient to suppress cell proliferation, the loss of both copies of the gene contributes to cancer formation. (09 Oct 1997) |
| recessive trait | See: dominance of traits. (05 Mar 2000) |
| recessive, x-linked | A gene on the X chromosome that expresses itself only when there is no different gene present at that locus (spot on the chromosome). For example, duchenne muscular dystrophy (dmd) is an x-linked recessive disorder. A dmd boy has the dmd gene on his sole x chromosome (and so is said to be hemizgous for dmd). Although it is much rarer, a girl can have dmd (by several different means as, for example, if she has the dmd gene on both her x chromosomes and so is homozygous for dmd). (12 Dec 1998) |
| kidney, polycystic, autosomal recessive | Rare genetic disorder with autosomal recessive inheritance characterised by multiple cysts in both kidneys and associated hepatic lesions. Serious manifestations are usually present at birth and there is high perinatal mortality. (12 Dec 1998) |
| acquired mutation | A change in a gene or chromosome that occurs in a single cell after the conception of the individual. That change is then passed along to all cells descended from that cell. Acquired mutations are involved in the development of cancer. (12 Dec 1998) |
| addition-deletion mutation | <molecular biology> A type of mutation that results from insertion or deletion of a single nucleotide into, or from, an open reading frame in the normal DNA sequence. Normally, the genetic code is read in the wrong frame, three nucleotides at a time, and the entire sequence downstream of the mutation, is translated into a polypeptide with a garbled amino acid sequence from the mutated codon onwards. These mutations may be induced by certain types of mutagens or may occur spontaneously and usually result in the generation, downstream, of nonsense, chain termination codons. Synonym: addition mutation, addition-deletion mutation, deletion mutation, reading-frameshift mutation. (21 Jun 2000) |

| amber mutation | <molecular biology> A mutation from a codon which codes for an amino acid into the amber codon UAG, which normally signals that the translation of mRNA into an amino acid chain should stop. The mutation causes the amino acid chain to stop forming before it is actually completed. (09 Oct 1997) |
