6. Why are well-defined reading frames critical in protein synthesis?
A. Without a well-defined reading frame, the peptide made from a given sequence could be completely different.
B. Without a well-defined reading frame, the resulting protein would be transported to the cell surface
C. Without a well-defined reading frame, the mRNA would be transcribed back into DNA.
D. Without a well-defined reading frame, the ribosome is unable to bind to the mRNA.

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
