Gene regulation during development is _____, which means that _____.
A)restrictive; genes are successively lost over time
B)restrictive; genes lose developmental potential over time
C)hierarchical; genes expressed at each stage control the expression of genes that act later
D)hierarchical; genes are turned on in a specific sequence, starting with totipotent and ending with multipotent
E)combinatorial; genes expressed at each stage control the expression of genes that act later

Question

Quizplus · Accepted Answer

Hierarchical gene regulation means that genes expressed at each stage control the expression of genes that act later, which is the case during development. However, neither A nor B accurately describe gene regulation during development, and D does not reflect the observed pattern of gene activation. Choice E is partially correct but does not specify that the gene regulation is hierarchical.
