We examined the ability of 2'-deoxy-2'-fluroarabinonucleoside 5'-triphosphates (2'F-araNTPs) to serve as substrates of various DNA polymerases. In addition, we also examined the ability of these polymerases to accept DNA-FANA (2'-deoxy-2'-fluoroarabinonucleic acids) chimeras as template strands while synthesizing a DNA or FANA-DNA complementary strand. We provide preliminary data demonstrating that 2'F-araNTPs are indeed substrates of several DNA polymerases, and that FANA-DNA chimeric templates are generally well recognized by these polymerase enzymes.

UI	MeSH Term	Description	Entries
D004259	DNA-Directed DNA Polymerase	DNA-dependent DNA polymerases found in bacteria, animal and plant cells. During the replication process, these enzymes catalyze the addition of deoxyribonucleotide residues to the end of a DNA strand in the presence of DNA as template-primer. They also possess exonuclease activity and therefore function in DNA repair.

D052156	SELEX Aptamer Technique	A method of generating a large library of randomized nucleotides and selecting NUCLEOTIDE APTAMERS by iterative rounds of in vitro selection.
