- 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.arrow_forwardName and describe the first four events (and associated enzymes) that happen during DNA replication at the DNA double helix (in correct sequence)arrow_forwardIllustrate some steps involved in DNA replication :Suppose the following base sequence was found in a segment of one strand of a DNA molecule: 3’ A-A-T-A-C-C-T-C-C-T-A-A-C-T 5’ What would be the bases in the complementary strand? Label the 3’ and the 5’ ends. Illustrate the DNA molecule below. Label the 3’ and the 5’ ends of both strands. Separate the above DNA molecule up to the seventh base. Add one primer for the leading strand complementary to the first base Adenine of the template strand. Add one primer for the lagging strand complementary to the seventh base Adenine of the template strand. Illustrate the DNA molecule. Label the 3’ and 5’ ends. Elongate the new strands up the seventh base by adding DNA bases complementary to the template strand. Illustrate the resulting DNA molecule. Label the 3’ and the 5’ ends of the template strands and the complementary strands. Elongate the new strands up the seventh base by adding DNA bases complementary to the template strand.
