DNA replication:

Correct answer: C. DNA polymerases

  • A. Locus
  • B. Meselson and Stahl
  • C. DNA polymerases
  • D. S form

Explanation

DNA polymerases are enzymes responsible for catalyzing the synthesis of DNA molecules from nucleotides during DNA replication. These enzymes work by adding nucleotides to the growing DNA strand in a complementary fashion, using one of the original DNA strands as a template. DNA polymerases also play crucial roles in DNA repair and other DNA synthesis processes in cells.
