Primase binds to the site of origin. C. DNA polymerase binds to the template strand. D. An RNA primer is synthesized. E. Incoming deoxynucleoside triphosphates are added to the growing strand.
Which of the following statements about DNA replication is INCORRECT? It is powered bythe hydrolysis of ATP. Each strand withinthe DNA double helix is used as a template for synthesis of a new strand. It requires that both strands of the double helix be separated from each other. It proceeds withthe addition of new nucleotides to the 3′ end of a growing DNA strand. It begins atmultiple origins of replication sites along eukaryotic chromosomes.
