Which event takes place first during DNA replication?

• a single-stranded RNA molecule is formed

• fragments are joined and breaks are fixed

• the DNA molecule "unzips" along weak hydrogen bonds

• bases are added and mistakes are checked for

Which is the first step of DNA replication?

• DNA Helicase unzips original DNA strand

• RNA Primase lays down RNA primer for new nucleotide bases.

• DNA polymerase builds new strands by bring in new nucleotide bases.
