sister chromatids as seen in the image below. Identify the structure known as the centromere based
on the image below.
A. Structure A
B. Structure B
C. Structure C
D. None of the Above
8. Before cell reproduction or mitosis can proceed, what is the correct sequence of steps that MUST
first occur?
A. Chromosome replication, chromosome checking and repair, growth
B. Replication of chromosomes, growth, duplication of cellular contents and organelles
C. Growth of cytoplasm, duplication of cellular organelles, chromosome replication

organelles
9. The graphic represents the different stages of the cell cycle. Specific genes within the DNA, called
inhibitors, stop the cell cycle in G1 phase. This process helps to keep the DNA unaltered and the
cells dividing at the correct rate. Certain chemicals in our environment may result in mutations of
cells' DNA that in turn prevent the inhibitors from halting the cell cycle. If this happens, _______
may result.
.
A. cancer
B. deformities
C. cell death
D. birth defects

A. Cytokinesis
B. G2.
C. Mitosis
D. Interphase.
13 Which of the following shows the correct sequence of the cell cycle?
