Put the following events describing the process of mRNA degradation by miRNA in sequential order.

1 the mRNA is degraded or translation of the mRNA is halted
2 an enzyme, Dicer, cleaves the precursor miRNA in small fragments
3 miRNA binds to the mRNA
4 one strand of the miRNA binds a protein complex, the other strand is degraded
5 a precursor miRNA forms a hairpin loop
Select one:

a. 3, 2, 4, 5, 1
b. 2, 5, 4, 1, 3
c. 5, 4, 2, 1, 3
d. 2, 5, 4, 3, 1
e. 5, 2, 4, 3, 1

Which organelle breaks down sugar molecules that supply energy to the cell ?

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.

True or false multiple lane changes must be done individually going through the same procedures for each lane change
