Draw three things (take your drawing cues from slides 11/12): (i) a gene with
two exons that encodes a small protein; (ii) the resulting unspliced transcript;
and (iii) the mature mRNA transcript (in this simple example, there is no
alternative splicing)
• The sense strand of the gene is (or we can say, the gene is encoded on) the
bottom (also known as the 3'-5" or Crick) strand
• The expression pattern (transcription) of the gene is specified by one upstream
enhancer we'll call enhA and one intronic enhancer we'll call enhB. Note that
enhancers consist of short (6-20 bp) DNA binding motifs and don't take up much
space on a gene locus diagram.
.
Be sure to label and graphically encode the following within the appropriate
part of your drawing. Do not draw anything that isn't requested.
CDS (coding sequence)
Exon 1 and Exon 2
Intron 1/2' (a single intron between exon 1 and 2)
5' and 3' UTRs (untranslated regions)
The polyadenylation signal
The TIS --- use this symbol but be sure it's pointing in the correct direction:
The (translational) start and stop codons
