(A) In order to replicate both DNA strands, E. coli synthesizes each strand in the opposite direction (one 5'-3', one 3'-5'), so they can be synthesized at once.
(B) Okazaki fragments are short DNA pieces that explain how DNA is synthesized on the leading strand.
(C) A primer strand in DNA replication is needed because it ensures the fidelity of the newly synthesized DNA strand.
(D) DNA repair mechanisms are essentially the same whether the DNA has minor damage or major damage.
