Question

which type of enzyme was used to produce the dna molecule in the figure above?
a restriction enzyme
dna polymerase
ligase
rna polymerase

Explanation:

1. Restriction enzyme: Cuts DNA at specific sites, not for synthesis shown.
2. DNA polymerase: Synthesizes DNA by adding nucleotides to a growing DNA strand, which is consistent with DNA - molecule production.
3. Ligase: Joins DNA fragments, not for primary synthesis.
4. RNA polymerase: Synthesizes RNA from a DNA template, not relevant for DNA - only synthesis here.

Answer:

DNA polymerase
