During translation , activated amino acids get linked to tRNA. This process is commonly called as

Answer

### Step-by-Step Solution:

1. **Understanding the Process**: During translation, amino acids are linked to transfer RNA (tRNA). This is a crucial step in protein synthesis, where the genetic code is translated into a sequence of amino acids.

2. **Identifying the Key Terms**: The process of linking an activated amino acid to tRNA is essential. The term "activated amino acid" refers to an amino acid that has been prepared for incorporation into a protein.

3. **Recognizing the Enzyme Involved**: The enzyme responsible for this linking process is called aminoacyl-tRNA synthetase. This enzyme catalyzes the reaction that attaches the amino acid to its corresponding tRNA.

4. **Naming the Process**: The process of linking the amino acid to tRNA is commonly referred to as "charging of tRNA" or "aminoacylation of tRNA." Both terms describe the same biochemical event.

5. **Choosing the Correct Answer**: Given the options:
- 1. Charging of tRNA
- 2. Discharging of tRNA
- 3. Aminoacylation of tRNA
- 4. Both 1 and 3

The correct answer is option 4, as both "charging of tRNA" and "aminoacylation of tRNA" are valid terms for this process.

### Final Answer:
The process of linking activated amino acids to tRNA during translation is commonly called **charging of tRNA** or **aminoacylation of tRNA**. Therefore, the correct answer is **option 4: both 1 and 3**.
