Imagine you are following a particular tRNA, called tRNAQ, through the process of translation in a eukaryote. Consider the steps of tRNAQ translation.

1. The polypeptide is transferred to tRNAQ.

2. tRNAQ binds the A site of the ribosome.

3. tRNAQ binds the P site of the ribosome.

4. The ribosome shifts, with tRNAQ still bound.

5. tRNAQ binds the E site of the ribosome.

In what order does tRNAQ go through the steps listed?

a. 3,4, 1, 4, 2, 4, 5

b. 2, 1, 4, 3, 4, 5

c. 3, 1, 4, 2, 4, 5

d. 5, 1, 4, 3, 4, 5

e. 2, 4, 1, 4, 2, 4, 5
