In DNA replication, when the DNA molecule separates into two strands:
a. it is possible to reconstruct perfectly all the information on the missing strand
because one strand carries all the information needed to construct its
complementary strand.
b. the rebuilding process begins, in which an enzyme connects the appropriate
complementary base to the exposed base.
c. the cell is ready for prophase.
d. All of the above are correct.
e. Only the first and second choices are correct. - ANSWER e. Only the first and
second choices are correct.
Which stage of the mitotic cell cycle is illustrated above?
a. prophase
b. anaphase
c. metaphase
d. telophase
e. interphase - ANSWER b. anaphase
Mitosis results in:
a. daughter cells with twice as much genetic material as the parent cell and a
unique collection of alleles.
b. eight daughter cells.
c. daughter cells with the same number and composition of chromosomes.
d. gametes.
e. genetically varied offspring. - ANSWER c. daughter cells with the same
number and composition of chromosomes.
,During meiosis but NOT during mitosis:
a. haploid gametes are produced that are identical in their allelic composition.
b. the cytoplasm divides.
c. chromosomes line up in the center of the cell during metaphase.
d. genetic variation among the daughter cells is increased.
e. two identical daughter cells are produced. - ANSWER d. genetic variation
among the daughter cells is increased.
