Question

what is the first step of dna replication? the dna molecule unzips along weak hydrogen bonds; a single - stranded rna molecule forms; free nucleotides bond together in the correct sequence; the dna molecule is translated to rna through an amino - acid

Explanation:

In DNA replication, the first step is the unwinding of the double - stranded DNA molecule along weak hydrogen bonds by helicase enzyme. This exposes the single - stranded DNA templates for replication.

Answer:

The DNA molecule unwinds along weak hydrogen bonds.
