DNA helicases 1 of 8 Catalyse the addition of new bases, complementary to the bases on each original strand. DNA polymerases 2 of 8 Formed that are identical to the original DNA molecule. Two DNA molecules 3 of 8 For the DNA to replicate, the __ ___ has to unwind and then seperate into two strands. Double helix 4 of 8 The ___ ___ holding the complementary bases together must be broken. Hydrogen bonds 5 of 8 Free ___ __ will then pair with their ___ which have been exposed as the strands seperate. 1) DNA Nucleotides 2) complementary bases 6 of 8 ____ are formed between them Hydrogen bonds 7 of 8 The new ___ join the adjacent ___ with phosphodiester bonds Nucleotides 8 of 8
