A skin cell and a pancreatic cell from the same person both contain the gene for insulin, but only the pancreatic cell makes insulin. What best explains this?
A cell produced by the cell cycle develops the shape, organelles and job of a particular cell type. What is this process called?
A muscle cell and a liver cell taken from the same person contain the same DNA sequence.
During differentiation, a cell permanently deletes the genes it will not use.
A researcher finds the DNA of a mouse muscle cell and a mouse liver cell to be identical, but the two cells contain very different sets of mRNA molecules. What does this result show?
The nucleus of an adult sheep's mammary gland cell was placed into an egg cell whose own nucleus had been removed, and the egg developed into the lamb Dolly. What does this show about a specialized cell?
Which statement best describes what changes as a cell differentiates?
Cells at the base of the epidermis divide throughout life and produce new skin cells, but they never produce nerve cells or liver cells. How are these dividing cells best described?
Which cells are able to differentiate into every cell type found in the human body?
The tip of a plant root contains a region of small, unspecialized cells that keep dividing and producing new root tissue throughout the plant's life. What is this region called?
Cell line A grown in a lab produced nerve, muscle and blood cells. Cell line B produced only red blood cells, white blood cells and platelets. Which conclusion is best supported?
Stem cells from umbilical cord blood are transplanted into a leukemia patient whose bone marrow has been destroyed. Why can these cells help the patient?
Identical cells from an early embryo are split between two dishes. A growth factor from developing bone is added to one dish only, and those cells become bone-forming cells. What does the result show?
In a developing embryo, a cell moved next to nerve tissue becomes a nerve cell, while the same kind of cell moved next to skin tissue becomes a skin cell. What does this show?
In many turtle species, the temperature at which the eggs are incubated determines whether an embryo develops as male or female. What does this best show?
Stem cells kept in a dish of nutrient solution with no added signaling chemicals keep dividing but stay unspecialized. What is the best explanation?
Which of these is an environmental signal that can trigger a stem cell to differentiate?
A mature human red blood cell has no nucleus. What follows from this?
Nerve cells damaged in a spinal cord injury are usually not replaced. Which feature of mature nerve cells best explains this?
Doctors treating damaged heart muscle often prefer stem cells taken from the patient's own body rather than from a donor. What is the main advantage?
