Question

dna replication
helicase
unwinds and unzips dna
dna polymerase
bonds new nucleotides onto original strands.
these enzymes open the dna ladder and bond new nucleotides strands onto the original strands of nucleotides.
directions: drag and drop these enzyme labels to the correct box.
original strand
new strand
new strand
original strand

Explanation:

The diagram shows DNA replication. Helicase unwinds/unzips DNA (matches the red enzyme separating the double helix). DNA polymerase bonds new nucleotides to original strands (matches the gray enzymes adding new strands).

Answer:

• Red enzyme box: Helicase
• Gray enzyme boxes: DNA Polymerase
