Protein Synthesis Cartoon Activity
In groups of three or four, you will make a six-step cartoon of protein
synthesis on the white-erase board provided. All of the bold terms must
be labeled on your cartoon. You may use analogies to represent the
structures rather than the structure themselves. Once it is approved by
the teacher, copy the cartoon into the left-side of your IntNB.
Transcription must include:
1. Helicase unzipping DNA at the gene of interest
2. RNA polymerase matching RNA nucleotide bases to DNA, using
one side as a template.
3. The mRNA strand being created. It now compliments the original
DNA strand (G-C and A-U). Show complimentary base pairs.
4. Ligase helping the strand of DNA to close again.
5. mRNA strand moving out of nucleus to ribosomes, DNA zipping up.
Translation must include:
1. Ribosomes attaching to the “start” codon of mRNA (AUG), signaling
the beginning of the protein chain.
2. mRNA codons matching to corresponding tRNA anticodons and
appropriate amino acids being strung together.
3. Dehydration synthesis occuring between the amino acids, and they
join, making a protein chain with peptide bonds in between.
4. Ribosomes detach when they come across a “stop” codon (UAA,
UAG, UGA). Protein synthesis is complete.
Total points will be assessed in your IntNB next class period.
15 points for correctly labeling key players in protein synthesis.
5 points for neatness and overall appearance (including 4 + colors)
5 points for creativity!
