Question

1) The Shine-Dalgarno sequence in bacteria ________.

a)is a consensus sequence involved in the termination of translation

b)is a purine-rich consensus sequence found in the 16S rRNA subunit

c)is a region of the tRNA molecule involved in formation of charged tRNAs

d)is a purine-rich consensus sequence found in the 5 UTR of the mRNA

e)is a pyrimidine-rich consensus sequence found in the 3 UTR of the mRNA

2)During translation initiation in prokaryotes, the amino acid on the initiator tRNA is

methionine (Met). IF-1. N-formylmethionine (fMet). added using ATP as the energy source. acetylated.

1. The answer is: d. is a purine-rich consensus sequence found in the 5 UTR of the mRNA.

The Shine-Dalgarno sequence in bacteria is a purine-rich consensus sequence found in the 5 UTR of the mRNA.

2. The answer is: N-formylmethionine (fMet).

During translation initiation in prokaryotes, the amino acid on the initiator tRNA is N-formylmethionine (fMet).
