DNA replication stages

• 1) enzyme DNA helicase breaks hydrogen bonds between complementary bases of two DNA polymer chains causing double helix to unwind
• 2) both strand of DNA then ac as templates for DNA replication
• 3) free floating nucleotides align opposite their complementary bases on both templates and hydrogen bonds form between the bases
• 4) DNA polymerase joins adjacent DNA nucleotides forming phosphodiester bonds between nucleotides to create new polymer chain of DNA
