Translation interactivity

Click the orange box that says Begin Activity

Read the passage, then answer

How does the cell make proteins from the information in the DNA?

Now, move onto the 2nd page.

Read about the transcription process, then use the interactivity to add 7 complementary RNA bases to the bottom line of DNA.

Which RNA nucleotide binds with Adenine (A) on the DNA?

• thymine

• uracil

• cytosine

• guanine

Why is an mRNA copy made of the DNA?

On page 3, read the passage on Translation and manipulate the Modeling Translation activity using the step-by-step button until it completes a protein.

How do the tRNA-mRNA interactions ensure that the amino acids are added in the correct order?

One triplet (codon) of mRNA is GCC. What is the nucleotide sequence for the complementary tRNA?

• GCC

• CGG

• AUG

• CCG

Move to page 4m Protein folding. Read the text and follow the instructions in the gray box to manipulate the interactivity. Generate a random protein for each new solvent.

Change the protein to all hydrophobic. What happens to the protein when placed in oil?

The cell is an aqueous environment. Where are the hydrophobic amino acids located in the folds of the protein?

Move on to page 5, read, and follow the instructions for the interactivity.

Describe the types of effects a DNA mutation could have on a protein.
