A microfluidic device for random fragmentation of DNA or RNA based on the application of a hydrodynamic shear force to these biomolecules is presented. Different from conventional fragmentation instruments, the microchip-based implementation allows molecul ...
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 ...
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)] ...
Replication (single-turnover) of pyranosyl-RNA (p-RNA) sequences can be accomplished reliably by template-directed ligation of 2',3'-cyclophosphates of short oligomers. The ligation process was studied using (mostly) octamers as templates and tetramers as ...
In this chapter, we have focused on the biochemistry of IRP-1 and the features which distinguish it from the related RNA-binding protein, IRP-2. IRP-1 is the cytoplasmic isoform of the enzyme aconitase, and, depending on iron status, may switch between enz ...
By automated synthesis, we prepd. hybrid oligonucleotides consisting of covalently linked RNA and p-DNA sequences (p-DNA = 3'-deoxyribopyranose (4'->2')-oligonucleotides). The pairing properties of corresponding hybrid duplexes formed from fully complement ...
It is proposed that catalysis by minerals and metal ions had a central role in the steps that led to the origins of life. In particular, the formation of biopolymers in the presence of water requires catalysis to compete with hydrolytic reactions. Catalysi ...
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 ...
The authors evaluated the RNA binding of all eight possible stereoisomers of LNA. Synthesis of "a-l-xylo-LNA" has been accomplished and the remaining four stereoisomers, all enantiomers of the four synthesized diastereoisomers, are indirectly evaluated b ...
