Question

The Shine-Dalgarno sequence in bacteria ________.

a. is a pyrimidine-rich consensus sequence found in the 3' UTR of the mRNA
b. is a purine-rich consensus sequence found in the 5' UTR of the mRNA
c. is a purine-rich consensus sequence found in the 16S rRNA subunit
d. is a region of the tRNA molecule involved in formation of charged tRNAs
e. is a consensus sequence involved in the termination of translation

Answer 1

Option B

Step-by-step explanation:

This sequence is a region on the found in the 5' UTR region on the mRNA that is composed of about 3-9 purine rich nucleotides. These forms complimentary bad pairs with the pyrimidine rich regions on the 16S ribosomal RNA of the 30S small subunit initiating translation in the bacteria
