Enzyme helping in combining amino acid to its particular tRNA in translation is

Options

A. tRNAase
B. Aminoacyl tRNA synthetase
C. Acyladenylate enzyme
D. Peptidyl transferase

Answer

To solve the question regarding the enzyme that helps in combining amino acids to their corresponding tRNA during translation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Role of tRNA in Translation**:
- tRNA (transfer RNA) is crucial in the process of translation, where it helps in decoding the mRNA (messenger RNA) sequence into a polypeptide chain (protein). Each tRNA molecule carries a specific amino acid that corresponds to a codon on the mRNA.

2. **Identifying the Enzymes Involved**:
- The question provides four options for enzymes that could be involved in this process. We need to analyze each option to determine which one is responsible for attaching amino acids to tRNA.

3. **Evaluating Each Option**:
- **tRNAase**: This enzyme is involved in the processing of tRNA, not in attaching amino acids to tRNA.
- **Aminoacyl-tRNA synthetase**: This enzyme catalyzes the attachment of an amino acid to its corresponding tRNA, a process known as aminoacylation. This is the enzyme we are looking for.
- **Acyl adenylate enzyme**: This enzyme is involved in the metabolism of fatty acids and does not play a role in amino acid-tRNA attachment.
- **Peptidyl transferase**: This enzyme catalyzes the formation of peptide bonds between amino acids during protein synthesis but does not attach amino acids to tRNA.

4. **Conclusion**:
- The enzyme that specifically helps in combining amino acids to their respective tRNA is **aminoacyl-tRNA synthetase**. Therefore, the correct answer is the second option.

### Final Answer:
The enzyme that helps in combining amino acids to their particular tRNA in translation is **aminoacyl-tRNA synthetase**.
