Plant biologists have developed an antisense gene that retards ripening in tomatoes, greatly extending the shelf life of the fruit. What might such a gene code for

Options

A. A gene for a hormone that slows fruit ripening
B. A complementary mRNA that would pair with and block the translation of mRNA for the fruit ripening enzyme
C. A gene for a transcription factor that would block the transcription of the fruit-ripening gene
D. A mutated version of the ripening gene that would not promote ripening

Answer

B
