Solution

The correct option is D Shine - Dalgarno sequence
In prokaryotes, the ribosomes binding site (RBS) on the mRNA is called the Shine-Dalgarno sequence. It is present in the 5' UTR region. It is made up of purine bases.
A. Hogness sequence is also called the TATA box and these are present in the promoter region of a gene on the DNA of eukaryotes. It is required for transcription.
B. Shine-Dalgarno sequence is on the prokaryotic mRNA required for the translation.
C. The Pribnow sequence is on the DNA of bacteria required for the transcription.
D. TATA box is also called the Hogness Sequence.
Hence, the correct answer is 'Shine-Dalgarno sequence'
