DNA replication occurs during which of the following phases of the cell cycle?
G1
S
G2
Mitosis
Before DNA can be replicated by DNA polymerase enzymes, it must first separate –
behind the deoxyribose sugars
between the nitrogen bases
underneath the phosphate groups
between the carbon atoms

Cytokinesis is the final stage of the cell cycle and it is characterized by the creation of two –
daughter cells
DNA mutations
nuclei
sets of chromosomes
Muscle cells require large amounts of energy. This explains why muscle cells contain a greater than average number of –
nuclei
mitochondria
vacuoles
lysosomes
Bone cells are different than brain cells because bone cells –
do not undergo cell division
cannot maintain homeostasis
contain charged ions
express different genes
The cells within a multicellular organism contain the same set of DNA, but two cells might produce a very different set of proteins. How is this possible?
Cells can have different sets of mRNA molecules because different genes are expressed.
Different cells produce different proteins based on the amino acids they can absorb.
Ribosomes translate mRNA strands differently depending on the type of cell they are in.
Viral infections can alter the way eukaryotic cells translate their genes into proteins.
Which of the following is identical in a skin cell and a muscle cell from the same individual?
cellular shape
amount of ATP
genetic material
cell function
While all of the cells in an individual are derived from a single cell, they can differentiate to take on many different types of structure and function. Cells can become specialized because –
mutations can alter the molecular structure of cell membranes
each cell expresses a different combination of genes
scientists have discovered how to alter the DNA sequences of humans
different cells utilize various forms of RNA nucleotides
Stem cells can replace specialized cells within damaged tissue. Once they are in place, stem cells receive chemical signals which activate the appropriate set of genes. This demonstrates that which of the following plays a role in cell differentiation?
radiation
environment
antibodies
blood type
What are the stages of mitosis in order?
P-M-T-A
T-A-M-P
P-M-A-T
A-T-M-P
