How does DNA replication occur in a precise manner to ensure that identical genetic information is put into the new chromatid? See Figures 8.12 and 8.13. FIGURE 8.12 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule contains one new strand and one old strand. This mechanism is called semiconservative replication. FIGURE 8.13 A close-up look at the process of DNA replication. (a) As the strands uncoil, bases are added to the newly synthesized strand by complementary base pairing with bases in the template strand. The new bases are linked together by DNA polymerase. (b) DNA synthesis can proceed only in the 5 3 direction; newly synthesized DNA on one template strand is made in short segments and linked together by the enzyme DNA ligase.

Which of the following most correctly describes a process that occurs during DNA replication? Group of answer choices Replication of the lagging strand occurs in the 5' → 3' direction—the leading strand in the 3' → 5' direction. Replication is continuous on the lagging strand and discontinuous on the leading strand. Okazaki fragments are DNA fragments synthesized on the lagging strand. DNA polymerase adds dNTP monomers in the 3′–5′ direction. Replication is continuous on the lagging strand and discontinuous on the leading strand.

In DNA replication, the fundamental reason that Okasaki fragments are produced is that Group of answer choices DNA replication can proceed only in the 5’ to 3’ direction replication on the leading strand is slower than replication on the lagging strand DNA polymerase tends to slip while replicating the lagging strand DNA polymerase has to alternate between the leading and lagging strands during replication none of these are true.

Refer to the picture above and indicate your answers. 6. DNA polymerase is adding the nucleotides to the top strand continuously--that means the top strand is the (leading or lagging) strand. 7. The bottom strand has short segments which are added discontinuously. This is the (leading, lagging) strand.…
