A slash chord is so called because the two letters of the symbol are separated by a forward slash, e. g. G/B, F/G, G/C.... The left-hand letter is the chord symbol while the right-hand letter(after the slash) is the bass note. When the bass note of the chord is contained within the triad then the slash chord can be identified as an inversion... When the bass note is not included in the left-hand chord symbol then the slash chord can be identified as a modal chord. 2, record 1, English, - slash%20chord

This is central to a theory of aging first developed by G. C. Williams in 1957. Williams suggested that some genes responsible for increased fitness in the younger, fertile organism contribute to decreased fitness later in life. One such example in male humans is the gene for the hormone testosterone. In youth, testosterone has positive effects including reproductive fitness but, later in life, there are negative effects such as increased susceptibility to prostate cancer. 1, record 3, English, - antagonistic%20pleiotropy

[...] la pléiotropie antagoniste a été proposée en 1957 par Williams. Comme son nom l'indique, elle fait appel à des mutations pléiotropes, c'est-à-dire capables d'influencer plusieurs caractères structuraux ou fonctionnels d'un même organisme. Les mutations envisagées par l'auteur ont des effets contrastés sur les individus en fonction de leur âge: elles favorisent la viabilité des individus jeunes, mais affaiblissent les individus âgés. La sélection naturelle aurait retenu ces mutations parce que les avantages qu'elles procurent aux jeunes l'emportent sur les inconvénients qu'elles occasionnent chez les vieux. 1, record 3, French, - pl%C3%A9iotropie%20antagoniste

("Unusual" means a base other than A, G, C, or U.) Many of the unusual bases differ from normal bases by the presence of one or more methyl(-CH3) groups. Most, if not all, of the methyl groups are enzymatically added after the nucleotides are linked together by 3’-5’ phosphodiester linkages. Very probably, the other unusual bases also arise by the enzymatic modification of a preexisting polynucleotide. The function of the unusual bases is not yet clear. They are not limited to alanine tRNA but occur in varying proportions in all tRNA molecules. Our only hint of their role is the fact that several unusual bases cannot form conventional base pairs. Some of the unusual bases may thus have the function of disruption double-helical hairpin regions, thereby exposing free keto and amino groups which can then form secondary bonds. Depending upon the specific bases, the free groups may form secondary bonds to template RNA, to a ribosome, or to the enzyme needed to attach a specific amino acid to its specific tRNA molecule. [Examples of those rare nucleotides are : Inosine, 1-methylinosine, N2-dimethylguanosine, 1-methylguanosine, Ribothymidine, Dihydrouridine and Pseudouridine]. 1, record 6, English, - unusual%20base

Les deux classes de bases trouvées dans tous les mononucléotides sont dérivées de corps aromatiques hétérocycliques appelés purine et pyrimidine. La purine dérive elle-même de la pyrimidine par la fusion d'un cycle pyrimidine et imidazole. Les trois bases pyrimidiques les plus communes sont : l'uracile, la thymine et la cytosine, désignées couramment par U, T et C respectivement. Les bases puriques intervenant le plus souvent comme composantes des mononucléotides sont l'adénine et la guanine, respectivement désignées par A et G. Il existe [aussi] de nombreuses bases rares, telles que la 5-méthylcytosine, ou la 5-hydroxyméthyl-cytosine, [l'ionosine, la pseudouridine, etc...] Le rôle de ces bases rares n'est pas clair pour l'instant. Elles (...) existent en proportions variables dans toutes les molécules de tARN. Seul indice connu sur leur rôle possible, ces bases rares ne peuvent pas s'apparier de la manière habituelle. Certaines de ces bases rares pourraient donc avoir pour fonction de provoquer l'ouverture de quelques régions en épingle à cheveux de la double hélice, exposant ainsi des groupements cétones et aminés libres susceptibles de former des liaisons secondaires. Selon la nature des bases exposées, ces groupements libres pourraient former des liaisons secondaires avec la matrice d'ARN, avec le ribosome ou avec l'enzyme qui attache l'acide aminé à son tARN spécifique. 1, record 6, French, - base%20rare
