Which enzyme is responsible for adding the free nucleotides to the replicating DNA?

Back

DNA polymerase

Front

Which is the first step?

• DNA Helicase unwinds original DNA strand
• RNA Primase lays down RNA primer for new nucleotide bases.
• DNA polymerase builds new strands by bringing in new nucleotide bases.
• Ligase knits together fragments on lagging strand
