Mutation of the Arabidopsis thaliana tRNA (Trp)(CCA) anticodon or of the A73 discriminator base greatly diminishes in vitro aminoacylation with tryptophan, indicating the importance of these nucleotides for recognition by the plant tryptophanyl-tRNA synthetase. Mutation of the tRNA (Trp)(CCA) anticodon to CUA so as to translate amber nonsense codons permits tRNA (Trp)(CCA) to be aminoacylated b...

national identity, an ever-changing and multidimentional phenomenon, is the product of a continuous historical process which has always been influenced by environmental conditions. the study of the comprising elements of national identity is the objective of another project of recognizing nations. national identity of iranians is rooted in two sets of beliefs: zoroastrianism, the ancient native...

The recently published discrete mathematical method, extended consensus partition (ECP), identifies nucleotide types at each position that are strictly absent from a given sequence set, while occur in other sets. These are defined as discriminating elements (DEs). In this study using the ECP approach, we mapped potential hidden identity elements that discriminate the 20 different tRNA identitie...

background: each group or profession has its own discourse. discourses create identity, support institutions and reproduce power relationships. professional identity of iranian nurses, which has recently had the opportunity to represent itself in social arena, needs investigation. this study aimed to make internal aspect of this identity clear. materials and methods: this study was conducted by...
