Exercise 19

The accompanying diagram shows a fully processed eukaryotic messenger RNA molecule hybridized to the transcribed strand of DNA of a gene that contains two introns. The diagram is oriented with the promoter region of the DNA at the left.

Use the letters that follow to label the location and/or boundaries of each segment. Some letters may be used several times, as appropriate; and some, which are not applicable, may not be used at all.
(a) 59 end
(b) 39 end
(c) Promoter region
(d) Attenuator
(e) Intron
(f) Exon
(g) Polyadenylation signal
(h) Leader region
(i) Ribosome-binding site
(j) Translation start codon
(k) Translation stop codon
(l) 59 cap
(m) Poly-A tail
