("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 2, 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 2, French, - base%20rare

Pin heads are of three types: flat, color ball (glass or plastic), and "T". The color ball has some advantage over the flat head in that it is easier to see and handle. A T-pin is convenient for heavy pile fabrics and loose knits; the head will not disappear into or slip through these fabrics. Standard pin point is sharp; ball-points are rounded to slip between yarns, which makes them a good choice for knits. 1, record 4, English, - pin%20head

Les têtes d’épingles sont de trois types : plates, rondes et colorées(en verre ou en plastique) et en T. L'épingle à tête ronde colorée est plus facile à repérer et à manier que l'épingle à tête plate. Les épingles en T conviennent aux tissus peluchés et aux lainages lâches. La pointe classique est aiguë; les épingles à pointe ronde passent entre les mailles sans les briser. Elles sont parfaites pour les lainages. 1, record 4, French, - t%C3%AAte%20d%26rsquo%3B%C3%A9pingle
