Ch. 10

The process by which a cell divides into two daughter cells is called

• cell division.
• metaphase
• interphase
• prophase-anaphase.

An advantage of sexual reproduction over asexual reproduction is that sexual reproduction 

• takes less time
• requires more time
• provides genetic diversity
• produces identical offspring

Which advantage of undergoing crossing over is illustrated in Figure 10–1 above?

• During DNA replication, the number of chromosomes is increased
• During DNA replication, the number of chromosomes stays the same.
• During cell division, each daughter cell will get the a mixture of genes from parents.
• During cell division, each daughter cell will get the same number of genes.

When during the cell cycle are chromosomes visible?

• only during interphase
• only when they are being replicated
• only during cell division
• only during the G1 phase

During which phase in the cell cycle does mitosis happen?

• G1 phase
• G2 phase
• M phase
• S phase

Which pair includes a phase of the cell cycle and a cellular process that occurs during that phase?

• G1 phase, DNA replication
• G2 phase, preparation for mitosis
• S phase, cell division
• M phase, cell growth

Which of the following is a correct statement about the events of the cell cycle?

• Nothing happens during the G1 and G2 phases.
• DNA replicates during cytokinesis.
• The M phase is usually the longest phase.
• Interphase consists of the G1, S, and G2 phases.

Cell division is represented in Figure 10–3 by the letter

• A
• B
• C
• D

The structure labeled A in Figure 10–5 is called the

• centromere
• centriole
• sister chromatid.
• spindle

The structures labeled B in Figure 10–5 are called

• centromeres
• centrioles
• sister chromatids.
• spindles
