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 ...
A review and discussion, with 42 refs. Base pairing in p-RNA (b-D-ribopyranosyl-(4'->2')-oligonucleotides) is not only stronger than in DNA and RNA, but also more selective in the sense that it is strictly confined to the Watson-Crick mode. Homopurine sequ ...
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 ...
Telomerase is composed of protein and RNA. The RNA serves as a template for telomere DNA synthesis and may also be important for enzyme structure or catalysis. We have used the presence of conserved sequence elements in the promoter and template regions to ...
Telomerase is the ribonucleoprotein enzyme responsible for the replication of chromosome ends in most eukaryotes. In the ciliate Euplotes aediculatus, the protein p43 biochemically co-purifies with active telomerase and appears to be stoichiometric with bo ...
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)] ...
The 5'-terminal sequence in the DNA of the parvovirus minute virus of mice (MVM) is a palindrome. It can form a hairpin, the stem of which is entirely base-paired except for three consecutive unpaired nucleotides which form a bubble. Since this structure i ...
A review with 39 refs. Qual. conformational anal. of the entirety of conceivable hexo- and pentopyranosyl oligonucleotide systems derived from the diastereoisomeric aldohexoses (CH2O)6 and aldopentoses (CH2O)5 predicts the existence of a variety of pairing ...
Methods for amplification and sequencing of at least one nucleic acid comprising the following steps: (1) forming at least one nucleic acid template comprising the nucleic acid(s) to be amplified or sequenced, wherein said nucleic acid(s) contains at the 5 ...
We describe a new procedure to identify RNA or DNA binding sites in proteins, based on a combination of UV cross-linking and single-hit chemical peptide cleavage. Site-directed mutagenesis is used to create a series of mutants with single Asn-Gly sequences ...
