Think of a corn cell that is genetically
modified to contain the Bt gene and a
corn cell that is not modified.
◦ In what ways are the cells similar?
◦ In what ways are the cells different?

Protein synthesis is the process in which
a cell makes a protein. It has two phases.
Transcription is the first phase, where
DNA is converted into mRNA.
Translation is the second phase, where
the mRNA is converted to tRNA and a
protein molecule is assembled.


As you view the simulation, be sure to
correct the order of the Transcription and
Translation cards, as needed.
Activity 16: Protein Synthesis:
Transcription and Translation
Procedure
The correct card order is:

D, F, E, J, A, H, B, G, C, I

Procedure

Try different sorts of insertions, deletions,
substitutions, and frameshifts to see if you
can determine what the effects of various
mutations are.

Copy the chart from the student book in
your science notebook. Fill in the chart to
determine the amino acid sequence that
results from the transcription and
translation of the following nucleotide

One night while watching TV you hear a
newscaster say, “DNA mutations cause
damaged proteins.” Based on your work in
Part B, how would you respond to this
claim?
