Cyanogen bromide is employed in

Options

A. Genetic finger printing
B. Tissue culture
C. Synthesis of humulin
D. Hybridoma technology

Answer

**Step-by-Step Solution:**

1. **Understanding Cyanogen Bromide**:
- Cyanogen bromide (CNBr) is an inorganic compound that is colorless and solid. It is known for its ability to modify biopolymers and fragment proteins.

2. **Functions of Cyanogen Bromide**:
- It is primarily used to cleave peptide bonds in proteins, which allows for the fragmentation of proteins and peptides. This property makes it useful in various biochemical applications.

3. **Applications of Cyanogen Bromide**:
- One of the main applications of cyanogen bromide is in the immobilization of proteins. This process is essential in various biotechnological and pharmaceutical applications.

4. **Synthesis of Humulin**:
- Humulin is a synthetic form of insulin produced using recombinant DNA technology. Cyanogen bromide plays a role in the synthesis of this insulin by facilitating the necessary modifications and fragmentations of proteins involved in the process.

5. **Identifying the Correct Option**:
- Given the options:
1. Genetic fingerprinting
2. Tissue culture
3. Synthesis of humulin
4. Hybridoma technology
- The correct answer is option 3, as cyanogen bromide is employed in the synthesis of humulin.

**Final Answer**: Cyanogen bromide is employed in the synthesis of humulin (Option 3).
