On the primitive earth, polymers such as proteins and nucleic acids in aqueous suspension formed the spherical aggregates. These are called.

Options

A. primitosomes
B. liposomes
C. primitogens
D. coacervates.

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: The question refers to the early conditions on Earth when life was beginning to form. It mentions polymers such as proteins and nucleic acids that aggregated in aqueous suspension.

2. **Identifying the Key Term**: The spherical aggregates formed by these polymers are specifically referred to in scientific literature. The question asks for the term that describes these aggregates.

3. **Recalling Relevant Concepts**: In the study of the origin of life, scientists like Oparin and Haldane proposed theories regarding the formation of life from simple organic compounds. They suggested that these compounds could aggregate to form structures resembling living cells.

4. **Defining Coacervates**: The aggregates formed by proteins and nucleic acids in an aqueous environment are known as coacervates. These are colloidal droplets that can exhibit some properties of living cells, such as a boundary separating them from their environment and primitive metabolic activities.

5. **Conclusion**: Based on the understanding of the origin of life and the properties of these aggregates, the correct answer to the question is **coacervates**.

**Final Answer**: The spherical aggregates formed by polymers such as proteins and nucleic acids in aqueous suspension are called **coacervates**.
