Virtual Replication, Transcription and Translation Lab
Go to learn.genetics.utah.edu/content/begin/dna/ and click on “Build a DNA
Model”. Once at that website, click on “Start Building” and Build your DNA
model.
~Replication~
In a Molecule of DNA:
1. Adenine (A) pairs with ______________________
2. Thymine (T) pairs with ______________________
3. Cytosine (C) pairs with _____________________
4. Guanine (G) pairs with ______________________
How long will it take you to make one copy of a DNA molecule?____________________
When you are finished, signal your teacher to check it and stamp here:_________
~Transcription and Translation~
Now back to learn.genetics.utah.edu/content/begin/dna/ and click on “Transcribe and
Translate a Gene”.
You will see a screen that asks you “Are you ready to transcribe a DNA sequence and
translate it into a protein?”. Click to begin.
When transcribing an RNA molecule from a strand of DNA:
1. Adenine (A) pairs with ______________________
2. Uracil (U) pairs with ______________________
3. Cytosine (C) pairs with _____________________
4. Guanine (G) pairs with ______________________
5. Which triple codon signals the start of translation?

6. The triple codon of (AUG) transcribes into which amino acid?
7. The triple codon of (CUA) transcribes into which amino acid?
8. The triple codon of (GAC) transcribes into which amino acid?
9. The triple codon of (GUG) transcribes into which amino acid?
10. The triple codon of (UUC) transcribes into which amino acid?
11. The triple codon of (UAG) performs which action?
12. Each protein from particular arrangements of the ______ common amino acids; this
means that for a chain of just ______________ amino acids, there are over
__________________ possibilities!
Now back to learn.genetics.utah.edu/content/begin/dna/ and click on “What makes a
Firefly glow”.
1. Within the cell, where is DNA found?
2. What is transcription? Provide an example.
3. When transcription is complete, ______________ moves into the _______________.
4. Once in the cytoplasm, the mRNA is recognized by the cell’s protein-making
machinery, called the __________________.
5. The ______________ interprets the information and produce a string of amino acids.
This process is called _____________________.
6. What is translation? Provide an example.
7. In order to become a functioning enzyme, the string of _________________ must
bend to form a three-dimensional shape (a protein).
