Candy Transcription and Translation
Objectives:



To demonstrate how the sequence of DNA determines the sequence of mRNA transcribed.
To model the processes of transcription and translation.
To demonstrate how ribosomes use the code of mRNA to translate the genetic code.
Materials:
red Twizzlers, black Twizzlers, marshmallows toothpicks, paperclips, Smarties, pasta, packing puffs, cotton
balls, sticky Notes labels Other?
Prelab:
Where does transcription take place?_________________
The end product of transcription is ________________.
Where does translation take place? __________________
The final product of translation is _________________.
What are the main types of RNA and what is each of their function?
Materials:
red Twizzlers, black Twizzlers, marshmallows toothpicks, paperclips, Smarties, pasta, packing puffs, cotton balls, sticky
Notes labels Other?
RNA:
RNA has some key differences from DNA. List them below and make a key for the 4 RNA nucleotides. Paste a picture
of the 4 RNA nucleotides clearly labeling: ribose, base, phosphate group and nucleotide name.
Transcription:
Get your original DNA model or rebuild it using the pictures from the DNA structure and replication lab.
Transcription is the process of copying the genetic information from DNA into a usable copy of mRNA. Make
a model clearly indicating this process make sure to include in your model representations of the following:
nucleus, cytoplasm, template stand, coding strand, mRNA nucleotides, RNA polymerase, mRNA. Paste a
picture(s) of your model below.
Translation:
Make a model demonstrating the process of translation. Your model should include where in the cell translation
takes place and the final product of translation. Your model should include the following: ribosomes, codons,
tRNA with anti-codons and appropriate amino acid, forming polypeptide and completed polypeptide. Paste a
labeled picture(s) depicting the process of translation below.
