Guida verificata passo dopo passo1
Understand the process of DNA replication: DNA replication is the process by which a cell duplicates its DNA before cell division. It involves several enzymes working together to ensure accurate copying of the genetic material.
Identify the role of each enzyme mentioned: Helicase unwinds the DNA double helix, primase synthesizes a short RNA primer to provide a starting point, DNA polymerase adds new nucleotides to the growing DNA strand, and ligase seals gaps between DNA fragments.
Focus on the enzyme responsible for adding nucleotides: DNA polymerase is the enzyme that synthesizes the new DNA strand by adding complementary nucleotides to the template strand.
Recall the Amoeba Sisters video recap: The video emphasizes the role of DNA polymerase in elongating the DNA strand during replication, highlighting its importance in ensuring the accuracy of the process.
Conclude the answer: Based on the information provided and the roles of the enzymes, DNA polymerase is the correct enzyme responsible for adding new nucleotides to the growing DNA strand during DNA replication.
