The following figure shows a small
region of a chromosome. Using the DNA shown below and the genetic
code, show the products of transcription and
translation. The arrow represents the promoter, the “+1”
is below the first base pair that is transcribed and the “t”
represents the transcriptional terminator (i.e. this base pair is
not transcribed). The Shine-Delgarno sequence is underlined and
labeled “SD”. Label 5’ and 3’ ends and N- and C-termini where
appropriate. How many tRNA molecules are used in the synthesis of
the polypeptide product? Is this DNA from a
eukaryote or prokaryote? Why?
Draw and label a base-pair
substitution mutation in the DNA molecule that results in
a missense mutation. Now draw and label a mutation
that will result in a frameshift mutation. What kind of mutation is
it?
