The enzyme that adds nucleotides to form new strands of DNA isMultiple Choiceamylase.transcriptase.ligase.helicase.DNA polymerase.

Break Down the Problem

1. Identify the function of the enzymes listed.
2. Determine which enzyme specifically adds nucleotides to form new strands of DNA.

Relevant Concepts

1. Amylase: An enzyme that breaks down starches into sugars.
2. Transcriptase: An enzyme involved in the synthesis of RNA from a DNA template (specifically RNA polymerase).
3. Ligase: An enzyme that connects two strands of DNA or RNA by forming a bond.
4. Helicase: An enzyme that unwinds the DNA double helix.
5. DNA Polymerase: An enzyme that adds nucleotides to a growing DNA strand during DNA replication.

Analysis and Detail

• From the enzyme functions listed, we can analyze that:
  • Amylase does not play a role in DNA synthesis.
  • Transcriptase transcribes DNA into RNA, not DNA synthesis.
  • Ligase connects DNA fragments; it does not add nucleotides.
  • Helicase unwinds the DNA but does not synthesize DNA.
  • DNA Polymerase is responsible for adding nucleotides to form new DNA strands during DNA replication.

Verify and Summarize

After reviewing the functions of each enzyme, it's clear that DNA Polymerase is the enzyme responsible for adding nucleotides to form new strands of DNA.

Final Answer

DNA polymerase is the enzyme that adds nucleotides to form new strands of DNA.
