what enzyme is used to attach dna strands
DNA polymerase adds a new strand of DNA by extending the 3' end of an existing nucleotide chain, adding new nucleotides matched to the template strand one at a time via the creation of phosphodiester bonds.NA strands have a directionality, and the different ends of a single strand are called the 3' (three-prime) end and the 5' (five-prime) end. By convention, if the base sequence of a single strand of DNA is given, the left end of the sequence is the 5' end, while the right end of the sequence is the 3' end.
