The Significance of the Shine-Dalgarno Sequence is That It Is

Question

The significance of the Shine-Dalgarno sequence is that it is the site where
A) RNA polymerase binds to begin transcription.
B) a ribosome binds so that it can initiate translation.
C) DNA polymerase binds to begin chromosome replication.
D) the tRNA binds to the mRNA in translation.
E) DNA polymerase begins synthesis of the Okazaki fragments on the lagging strand.

Accepted Answer

The Shine-Dalgarno sequence is a short nucleotide sequence found in prokaryotic mRNA molecules that signals to the ribosome where to initiate translation. The ribosome binds to the Shine-Dalgarno sequence, positioning itself for translation initiation.
