d. source of nucleotides
An old DNA strand is used as a _____ for the assembly of a new DNA strand.?
This is part of the DNA replication process. The enzyme helicase breaks apart adjoined DNA strands. And then the enzyme DNA polymerase uses an old strand as a template to make a new strand.
Reply:template. The strands of the old DNA are separated, and each becomes half of a new DNA duplex.
Reply:I would argue that both complement and template are correct. the structure of the new strand is dependent on the nucleotides that are present on the template strand (old strand). The template is the complementary bases to the new strand.
