26. A method for controlling the incorporation of nucleotides into a polynucleotide strand, comprising the steps of:
-
(a) providing a nucleotide having a ribose or deoxyribose sugar moiety, wherein an enzymatically removable protecting group is attached to the 3′
oxygen atom of the ribose or deoxyribose sugar moiety of the nucleotide;(b) providing a first enzyme to incorporate the nucleotide into the strand, whereby the protecting group prevents incorporation of another nucleotide into the strand; and (c) providing a second enzyme to remove the protecting group to expose a 3′
-OH group on the first nucleotide, thereby allowing incorporation of another nucleotide into the strand;(d) repeating steps (a) to (c) at least once; thereby controlling the incorporation of nucleotides into the strand. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A kit, comprising:
-
(a) a nucleotide having a ribose or deoxyribose sugar moiety, wherein an enzymatically removable protecting group is attached to the 3′
oxygen atom of the ribose or deoxyribose sugar moiety of the nucleotide;(b) a first enzyme that is engineered to incorporate the nucleotide into a polynucleotide strand, whereby the protecting group of the nucleotide prevents incorporation of another nucleotide into the strand; and (c) a second enzyme to remove the protecting group to expose a 3′
-OH group on the incorporated nucleotide. - View Dependent Claims (46, 47, 48)
