What is the most likely result from mutating a prokaryotic Shine-Dalgarno sequence?
A)The translated protein would have different amino acids.
B)The mRNA would be less stable.
C)The ribosome would not be able to bind to the mRNA.
D)None of the above: prokaryotes do not have a Shine-Dalgarno sequence.

Mutating the Shine-Dalgarno sequence would affect the ability of the ribosome to properly bind to the mRNA, therefore inhibiting translation. It would not affect the amino acid sequence of the protein produced, nor the stability of the mRNA, which is more related to changes in the 5' and 3' untranslated regions. Prokaryotes do have a Shine-Dalgarno sequence, so D is not a valid option.
