................ proposed that there should be some mechanism by which the code can be read and also it can be linked to the amino acids during translation process.

Options

A. Crick
B. Avery
C. Owens
D. Orwell

Explanation

To answer the question, we need to identify the scientist who proposed a mechanism for reading the genetic code and linking it to amino acids during the translation process.

### Step-by-Step Solution:

1. **Identify the Context**: The question asks about a mechanism related to the translation process in protein synthesis, specifically how the genetic code is read and linked to amino acids.

2. **Recall Key Scientists**: We need to consider the options provided: Crick, Avery, Owens, and Orwell.

3. **Focus on Francis Crick**: Francis Crick is well-known for his contributions to the understanding of DNA and protein synthesis. He, along with James Watson, proposed the double helix structure of DNA and later worked on the concept of how genetic information is translated into proteins.

4. **Understanding the Proposal**: Crick proposed that there should be an "adapter molecule" that reads the genetic code (mRNA) and links it to the corresponding amino acids during translation. This adapter molecule is known as transfer RNA (tRNA).

5. **Conclusion**: Based on the information, the correct answer to the question is **Francis Crick**.

### Final Answer:
The scientist who proposed that there should be some mechanism by which the code can be read and linked to amino acids during the translation process is **Francis Crick**.
