The assertion is true. During DNA replication, the enzyme DNA Polymerase covalently joins nucleotides to create new DNA strands.
Semi-conservatism applies to DNA replication. The double helix's strands serve as models for the creation of new, complementary strands. DNA polymerases, which require a template and a primer (beginning) and synthesise DNA in the 5' to 3' orientation, are the enzymes responsible for creating new DNA.
Only strands or primers of DNA or RNA that are base paired with the template can have nucleotides added to them by the DNA synthesis enzyme, DNA polymerase. The covalent binding of the incoming nucleotide to the primer requires the enzyme DNA polymerase.
Therefore, we can conclude that the proposition is accurate. During DNA replication, the enzyme DNA Polymerase covalently joins nucleotides to create new DNA strands.
