Question

(use the diagram to the right for 23-25)

1. what process is this?
2. how do you know?
3. what does # 2 represent?
4. what does #3 represent?

Explanation:

Question 27

The diagram shows a ribosome, tRNAs carrying amino acids, and an mRNA strand. This setup is characteristic of translation, where the genetic code in mRNA is used to assemble a polypeptide chain (protein) using amino acids brought by tRNAs.

We know it's translation because there's a ribosome (the site of translation), mRNA (labeled as 1, the template), tRNAs (with anticodons) carrying amino acids (like Methionine, Phenylalanine, etc.), and the assembly of amino acids into a chain (labeled 3, a polypeptide). Translation is the process of converting mRNA's codons into a sequence of amino acids to form a protein, which matches the components shown (ribosome, mRNA, tRNAs, amino acids).

In the translation diagram, the number 2 is associated with each amino acid (Methionine, Phenylalanine, etc.) carried by tRNAs. These are amino acids, which are the building blocks of proteins and are brought by tRNAs to the ribosome to be added to the growing polypeptide chain.

Answer:

This process is translation.
