The reaction of d,l-5'-activated nucleotide of adenosine in the presence and absence of montmorillonite gave 60:40 and 96:4 ratios, resp. of the d,d- and l,l:d,l- and l,d-dimers. [on SciFinder (R)] ...
Telomerase extends chromosome ends by iterative reverse transcription of its RNA template. Following the addition of each telomeric repeat, the RNA template and the telomeric substrate reset their relative position in the active site provided by the telome ...
The detn. of the soln. structure of small non-natural oligopeptides and oligonucleotides by NMR, which is one of the main research topics of our group, is illustrated on the example of an 8-mer p-DNA duplex. P-DNA, the 3'-desoxy analog of p-RNA, forms an h ...
In contrast to DNA-related research, RNA-related research is limited by the availability of synthetic sequences. Recent improvements in chem. synthesis allow Xeragon AG to offer custom RNA sequences - up to 100mers - in high quantity and quality at an affo ...
Cross-correlated relaxation of multiple-quantum coherences in NMR was used to investigate hydrogen bonds in Watson-Crick base pairs, based on the interference between various relaxation mechanisms. [on SciFinder (R)] ...
A review, with 17 refs. Methods for the regioselective introduction of alkoxymethyl-groups into the 2'-O-position of 5'-O-dimethoxytritylated, nucleobase-protected ribonucleosides and for the N-alkyloxycarbonylation of adenine and guanine nucleosides were ...
In the ribosomal biosynthesis of proteins, the aminoacylated t-RNAs serve as carriers of the amino acids. A total synthesis of these biol. key-compds. would allow the site-specific incorporation of modifications within the t-RNA and attachment of any desir ...
High-density oligonucleotide arrays are among the most rapidly expanding technologies in biology today. In the GeneChip system, the reconstruction of the sample mRNA concentrations depends upon the differential signal generated by hybridizing the RNA to tw ...
Telomerase is a ribonucleoprotein enzyme that adds repetitive sequences to the ends of linear chromosomes, thereby counteracting nucleotide loss due to incomplete replication. A short region of the telomerase RNA subunit serves as template for nucleotide a ...
Telomerase uses a short stretch of its intrinsic RNA molecule as template for telomere repeat synthesis. Reverse transcription of the RNA template is catalyzed by the telomerase reverse transcriptase (TERT) protein subunit. We demonstrate that human telome ...
