Abstract:
A general strategy for purification of oligonucleotides synthesized by solid phase synthesis is described. It is based on a recently developed concept involving a bio-orthogonal inverse electron demand Diels-Alder reaction between trans-cyclooctene and tetrazine, termed 'click-to-release'. The strategy has been applied towards the synthesis and purification of a model hairpin RNA strand, as well as a 34 nt long aptamer.

Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

The Replisome
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...
