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

question 16

Multiple Choice

• A)mRNAs in general have short lifetimes;this is not a surprising finding.
• B)Each segment specified by pair-rule mRNAs is completely determined in the embryo in a very short time.
• C)Building an animal body requires a sequence of steps;each of these steps is precisely timed.
• D)Timing of pair-rule sequence determination is not as important as spatial signaling.
