Nucleoside Triphosphates - From Synthesis to Biochemical Characterization
Published on: April 3, 2014
Abstract:
Phosphorylation of N-acyl-5'-O-DMTr-d-nucleosides, or similarly protected DNA-dimers having a free 3'-OH group, with 2-chlorophenyl-0,0-bis(1-benzotriazolyl)phosphate affords reactive 3'-phosphotriester derivatives. The latter intermediates can be used, without further purification, for the synthesis of DNA-fragments on the controlled pore glass/long chain alkylamine support. Further, 2-cyano-1,1-dimethylethoxy dichlorophosphine proved to be very suitable for the preparation of 5'-phosphorylated DNA-fragments on the same type of solid support.

Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.
Phosphodiester Bonds Link Nucleotides Together
DNA and RNA are polynucleotides or long chains of nucleotides that are linked together. A nucleotide is...
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...
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 the...
Translesion DNA Polymerases
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...
ATP and Macromolecule Synthesis
Most macromolecules are composed of single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers.
