29. Answer
• It indicates shine Delgarno sequence
• The small subunit/IF3 complex binds to the mRNA.
Specifically, it binds to the sequence AGGAGG,
known as the Shine-Delgarno sequence, which is
found in all prokaryotic mRNAs.( Its required for the
initiation of protein synthesis)

40. PROBLEM
• The hypothetical „stimulin‟ gene contains two
exons that encode a protein of 100 amino acids.
They are separated by an intron of 100 bp
beginning after the codon for amino acid 10.
Stimulin messenger RNA has 5‟ and 3‟
untranslated regions of 70 and 30 nucleotides
respectively. A complementary DNA made from
mature stimulin RNA would have how many bp?
