Question

A student makes a model to compare the process of transcription and translation to the process of using a grocery store that prepares orders for customers. Based on the student's model and your knowledge of the biological process, which person or object represents tRNA?
Q
The shopper
The shopping cart
The grocery list
The cashier

Answer 1

In the model of comparing transcription and translation to a grocery store, the tRNA (transfer RNA) would be best represented by the shopping cart.

Here’s the reasoning:

• tRNA is responsible for transporting amino acids to the ribosome during translation, similar to how a shopping cart carries items in a grocery store.
• The grocery list would represent the mRNA, as it contains the instructions (or information) on what items are needed.
• The shopper would represent the ribosome, as they are the one that assembles or picks the items based on the list.
• The cashier could represent the process of finalizing the translation and ensuring that the order is complete, but they do not carry or transport items like tRNA does.

Thus, the shopping cart is the best analogy for tRNA in this scenario.
