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.

What enzyme prevents recoiling of the DNA strand while synthesis is occurring? DE Segment 2 proteins keep the two helixes apart. adds the new nucleotides to the parental strand to produce the DNA polymerase -DNA nucleotide Segment 1 DNA polymerase ? 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.…

New nucleotides can be added by the DNA polymerase only to the 3 end of the growing strand O. Synthesis of new DNA is catalyzed by the enzymes called DNA polymerases OD. DNA replication is semi-conservative OE. DNA replication proceeds continuously on both parental DNA strands.
