Question

arrange the steps of dna replication in the correct order, from the first step to the last. (2 points) two identical dna molecules are produced from the original molecule. the newly added nucleotides are joined to form a continuous strand. the dna double helix unwinds to expose the two strands. dna polymerase adds matching nucleotides to the template strands.

Explanation:

Step1: Identify the first step

The first step in DNA replication is the unwinding of the DNA double helix to expose the two strands. So the first step is "The DNA double helix unwinds to expose the two strands."

Step2: Identify the second step

After unwinding, DNA polymerase adds matching nucleotides to the template strands. So the second step is "DNA polymerase adds matching nucleotides to the template strands."

Step3: Identify the third step

Next, the newly added nucleotides are joined to form a continuous strand. So the third step is "The newly added nucleotides are joined to form a continuous strand."

Step4: Identify the last step

Finally, two identical DNA molecules are produced from the original molecule. So the last step is "Two identical DNA molecules are produced from the original molecule."

Answer:

1. The DNA double helix unwinds to expose the two strands.
2. DNA polymerase adds matching nucleotides to the template strands.
3. The newly added nucleotides are joined to form a continuous strand.
4. Two identical DNA molecules are produced from the original molecule.
