DNA TO PROTEINS & BIOTECHNOLOGY
Direction: The suggested time is about 15 minutes for answering a free response biology
question, which is worth 10 points. The parts within a question may not have equal weight.
Answers must be in essay form. Outline form is NOT acceptable. Labeled diagrams may be
used to supplement discussion, but in no case will a diagram alone suffice. It is important
that you read each question completely before you begin to write.
Question 1 (10 points)
The following sequence of DNA shows a portion of the human insulin genetic code. Use
the sequence to explain the following.
DNA Sequence: TAC AAA CAA TTA GTC GTG AAT
A. Explain the process of transcription using the
genetic code for insulin as an example. Your
discussion should include an explanation of
transcription referencing the actual mRNA
sequence for insulin.
B. Explain how the insulin protein is produced during translation. Be sure to reference
detailed steps in your explanation.
C. If the 4th A in the DNA sequence was changed to G, how is the amino acid sequence of
insulin affected.
