Question

Which enzyme is responsible for binding free floating nucleotides to dna strand

Answer 1

The enzyme is called polymerases.

Answer 2

 polymerases, of which there are many. Understanding which types of polymerases perform which functions under which circumstances will clarify the complexity of this topic. The processes of transcription, making RNA from DNA, and replication, copying DNA from DNA, are major functions that require polymerases to link nucleotides into long chains.
