Dideoxynucleotide vs. Deoxynucleotide

Dideoxynucleotidenoun

(biochemistry) Any nucleotide formed from a deoxynucleotide by loss of a second hydroxy group from the deoxyribose group

Dideoxynucleotidenoun

(biochemistry) Any oligonucleotide consisting of two deoxynucleotides

Dideoxynucleotide

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).

Deoxynucleotidenoun

Any nucleotide that contains a deoxy sugar
