Scientists Have Found That the Lifetimes of MRNAs Coding for Pair-Rule

question 27

Multiple Choice

Scientists have found that the lifetimes of mRNAs coding for pair-rule regulatory elements in Drosophila embryos may last only a few minutes. What does this suggest about the overall developmental plan of an animal body?

• A) The role of mRNAs is less important than the position of genes in chromosomes.
• B) Homeotic genes have greater impact in forming an embryo than mRNA from pair-rule genes.
• C) Building an animal body requires a sequence of precisely timed steps.
• D) Timing of pair-rule sequence determination is not as important as spatial signaling.
