Proteomics is study of

Options

A. Protobionts
B. Embryogensis
C. Veneral diseases
D. Proteins synthesised by a genome

Answer

### Step-by-Step Text Solution:

1. **Understanding the Term "Proteomics":**
- Proteomics is a branch of biology that focuses on the study of proteins, particularly their structures and functions.

2. **Identifying the Role of Proteins:**
- Proteins are essential macromolecules that are synthesized based on the information encoded in genes. Each protein has a specific function in the body, contributing to various biological processes.

3. **Connection to the Genome:**
- The genome refers to the complete set of genes or genetic material present in an organism. It is the blueprint that guides the synthesis of proteins.

4. **Analyzing the Options:**
- Option A: Protobions - This refers to primitive cell-like structures and is not related to proteomics.
- Option B: Embryogenesis - This is the study of embryo development and does not pertain to proteins.
- Option C: Venereal disease - This is related to diseases transmitted through sexual contact and is not connected to the study of proteins.
- Option D: Proteins synthesized by a genome - This accurately describes proteomics as it involves studying the proteins produced based on the genetic information.

5. **Conclusion:**
- Based on the analysis, the correct answer to the question "Proteomics is the study of" is **Option D: Proteins synthesized by a genome**.
