WebDNA is composed of 2 chains of nucleotides that form a double helix shape. The two strands are antiparallel. ... Also termed as chain termination or dideoxy method; This method uses dideoxynucleotide triphosphates (ddNTPs) chain terminators: which have an H on the 3’ carbon of the ribose sugar instead of the normal OH found in deoxynucleotide ... Dideoxynucleotides are chain-elongating inhibitors of DNA polymerase, used in the Sanger method for DNA sequencing. They are also known as 2',3' because both the 2' and 3' positions on the ribose lack hydroxyl groups, and are abbreviated as ddNTPs (ddGTP, ddATP, ddTTP and ddCTP).
