Which of the following is found in binary fission but not in mitosis?
a) duplicated chromosomes attach to the plasma membrane
b) replicated strands of DNA seperate
c) the result produces 2 nuclei
d) following the process, a membrane seperates the 2 copies
e) replication of DNA begins at an origin
What
is divided into four phases: G1(the period between mitosis and the initiation of nuclear
DNA replication), S (the period of nuclear DNA replica-tion), G2 (the period between the completion of nuclear
DNA replication and mitosis), and M (mitosis).

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_forwardIn which phase of the cell cycle does DNA replication occur? a.
