Which of the following describes an accurate order of events in<br/>translation?() A: Ribosomal translocation occurs before the first aminoacyl-tRNA<br/>molecule binds to the small subunit. B: Initiation of translation occurs only after the small subunit<br/>dissociates from the mRN C: The large subunit of the ribosome binds the mRNA before the small<br/>subunit. D: The first aminoacyl-tRNA molecule binds to the small subunit before<br/>the large subunit binds.

In __________________ signaling, a cell-surface-bound signal molecule binds to a receptor protein on an adjacent cell. During embryonic development, for example, such signaling method allows adjacent cells that are initially similar to become specialized to form different cell types. A: endocrine B: contact-dependent C: paracrine D: neuronal
