Question

This electron micrograph shows simultaneous transcription and translation in a bacterium. A and B represent two different genes from the bacterium’s chromosome. The protein being constructed is not visible in this micrograph. Some letters might not be used and others might be used more than once.

Which letter represents DNA that is not being transcribed?

[ Choose ]I    D    G    J   A   C   F   E   H    B

Which letter best represents a RNA molecule?

[ Choose ]   I    D    G    J    A    C    F    E       H    B

Which letter is closest to the 5’ end of the template strand of the B gene?

[ Choose ]I   D   G    J    A    C    F    E    H    B

Which letter is closest to the 5’ end of the non-template strand of the B gene?

[ Choose ]I    D     G    J    A    C    F    E    H    B

Which letter is closest to the 5’ end of the mRNA?

[ Choose ]I    D    G    J    A    C    F    E    H    B

Which letter is closest to the 3’ end of the mRNA?

[ Choose ]I    D    G    J    A    C   F    E    H     B

Which letter is closest to the ribosome that has been translating longer than any of the other ribosomes in view?

[ Choose ]I     D     G     J    A     C    F    E    H     B
