Question 33 2 pts Which of the following statements about the process of DNA replication is true? It involves the enzyme DNA ligase, which corrects point mutations. It utilizes DNA polymerase, which catalyzes the reaction that adds a new nucleotide to the growing strand. The sequence on the new strand is always identical to one of the old parent strands. Adenine pairs with guanine, and cytosine pairs with thymine. Question 34 2 pts The DNA base...
