Answer

To solve the question, we need to fill in the blanks with the correct terms related to the process of translation in protein synthesis.

### Step-by-Step Solution:

1. **Identify the first blank (I)**: The question states that something provides the template during translation. In the context of protein synthesis, the molecule that serves as the template for translation is **mRNA (messenger RNA)**. This is because mRNA is transcribed from DNA and carries the genetic information to the ribosome, where it is translated into a protein.

**Answer for (I)**: mRNA

2. **Identify the second blank (II)**: The next part of the question mentions something that brings amino acids and reads the genetic code. The molecule responsible for this function is **tRNA (transfer RNA)**. tRNA molecules carry specific amino acids to the ribosome and have anticodons that pair with the codons on the mRNA, ensuring that the correct amino acids are added to the growing polypeptide chain.

**Answer for (II)**: tRNA

3. **Identify the third blank (III)**: The final part of the question refers to something that plays a structural and catalytic role. In the context of translation, this role is fulfilled by **rRNA (ribosomal RNA)**. rRNA is a key component of ribosomes, which are the sites of protein synthesis, and it also has catalytic properties that facilitate the formation of peptide bonds between amino acids.

**Answer for (III)**: rRNA

### Final Answers:
- (I) mRNA
- (II) tRNA
- (III) rRNA
