Question

1. which claim about genes’ role in building proteins best fits considering the modeling activity you have just completed?

• claim 1: genes provide instructions and build proteins.
• claim 2: genes provide instructions for making proteins, but they do not build the proteins themselves.

Explanation:

To determine the correct claim, we recall the process of protein synthesis. Genes (DNA segments) contain the code (instructions) for making proteins. However, the actual construction of proteins is carried out by cellular machinery like ribosomes and tRNA, using the instructions from genes. So genes provide the instructions but do not directly build the proteins.

Answer:

Claim 2: Genes provide instructions for making proteins, but they do not build the proteins themselves.
