Question 6

Accepted Answer

A)   prophase
B)   telophase
C)   metaphase
D)   anaphase

Question 7

Question 8

The process of cell division is different for prokaryotic versus eukaryotic cells because

Accepted Answer

A)   prokaryotes have a circular DNA molecule.
B)   prokaryotic cells do not undergo cell division.
C)   prokaryotic cells are larger than eukaryotic cells.
D)   prokaryotic DNA contains different bases from those in eukaryotic DNA.

Question 9

Which of the following predicts a likely outcome of bypassing the G2 checkpoint in the cell cycle?

Accepted Answer

A)   Damaged DNA would be immediately replicated and passed on to the two daughter cells,giving rise to helpful,new alleles.
B)   Incompletely replicated DNA may be passed to the two daughter cells; these cells could be lacking specific genes or chromosomes and would likely not survive.
C)   The cell cycle would pause if cell size or nutrient supply is inadequate,DNA is damaged,or DNA replication is incomplete.
D)   The cell cycle would simply skip mitosis and go directly to G1 to start over.

B)   prostate cancer
C)   autism
D)   heart disease

Question 17

Gametes are produced by meiosis rather than mitosis because

Accepted Answer

A)   mitosis would produce too many sister cells.
B)   meiosis reduces the chromosome number so that zygotes produced will have one full genome.
C)   meiosis doubles the chromosome number so that each gamete has twice the usual number of genes.
D)   meiosis ensures that the gametes are identical to the cell that produced them.
