From a single fertilized ovum undergoing a series of rapid cell divisions, a human infant develops. The embryonic cells become specialized for a variety of functions. Which of these statements best describes how different cell types develop?
29

Each cell has multiple copies of DNA that are affected in different ways by the environment to change the function of the cell at regular intervals
Each cell type has only one chromosome containing the DNA needed for that cell type
Each cell type contains only the active parts of the DNA needed for that cell type
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells

Q2
As a fertilized egg divides, the cells differentiate because they —
metabolize sugars rapidly
contain a lipid bilayer
have specific genes activated
can clump together

Q3
Researchers Robert Briggs and Thomas King used ultraviolet radiation to destroy the nuclear DNA of frog eggs. Nuclei from adult skin cells and from tadpole-gut epithelial cells were cultured and then injected into eggs that had their nuclei destroyed. The results were tadpoles. Which conclusion is supported by the data from this investigation?
The transplanted DNA mutated during culturing
The DNA information for development was silenced in differentiated cells
The transplanted DNA functioned as the original nuclear DNA of the egg cell would have
The DNA from skin cells and epithelial cells was not transcribed

Q4
Cell differentiation is critical during embryonic development. The process of cell differentiation results in the production of many types of cells, including germ, somatic, and stem cells. Cell differentiation is most directly regulated by —
ATP
lipids
sugars
DNA
