When gemcitabine is incorporated into DNA it allows a native, or normal, nucleoside base to be added next to it. This leads to "masked chain termination" because gemcitabine is a "faulty" base, but due to its neighboring native nucleoside it eludes the cell's normal repair system ( base-excision repair ).
There is a large family of nucleoside analogue reverse transcriptase inhibitors, because DNA production by reverse transcriptase is very different from normal human DNA replication, so it is possible to design nucleoside analogues that are preferentially incorporated by the former. Some nucleoside analogues, however, can function both as NRTIs ...
The successful incorporation of a third base pair is a significant breakthrough toward the goal of greatly expanding the number of amino acids which can be encoded by DNA, from the existing 20 amino acids to a theoretically possible 172, thereby expanding the potential for living organisms to produce novel proteins.

DNA synthesis is the natural or artificial creation of deoxyribonucleic acid (DNA) molecules. DNA is a macromolecule made up of nucleotide units, which are linked by covalent bonds and hydrogen bonds, in a repeating structure.
The double-stranded structure of DNA provides a simple mechanism for DNA replication. Here, the two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase. This enzyme makes the complementary strand by finding the correct base through complementary base pairing and bonding it onto ...

A DNA construct is an artificially-designed segment of DNA borne on a vector that can be used to incorporate genetic material into a target tissue or cell. [1] A DNA construct contains a DNA insert, called a transgene , delivered via a transformation vector which allows the insert sequence to be replicated and/or expressed in the target cell.
