Question

The dna polymerase extends the primers into a new dna strand by.

Answer 1

adding nucleotides one by one

Step-by-step explanation:

A typical primer is about five to ten nucleotides long. The primer primes DNA synthesis, i.e., gets it started. Once the RNA primer is in place, DNA polymerase "extends" it, adding nucleotides one by one to make a new DNA strand that's complementary to the template strand.
