The essential life process (es) evolved around RNA is/are

Options

A. Metabolism
B. Translation
C. Splicing
D. All these

Answer

To answer the question regarding the essential life processes that evolved around RNA, we can break down the options provided and analyze each one:

### Step-by-Step Solution:

1. **Understanding RNA's Role**:
- RNA (Ribonucleic Acid) plays a crucial role in various biological processes. It is involved in the synthesis of proteins, which are essential for all cellular functions.

2. **Analyzing Each Option**:
- **Option A: Metabolism**:
- Metabolism encompasses all chemical reactions that occur within a living organism. RNA is involved in metabolic processes, particularly in the translation of mRNA to proteins, which are necessary for metabolic functions.

- **Option B: Translation**:
- Translation is the process where ribosomes synthesize proteins from mRNA. This process is directly dependent on RNA, as mRNA carries the genetic information needed to produce proteins.

- **Option C: Splicing**:
- Splicing is a process that modifies the pre-mRNA transcript by removing introns and joining exons together. This process is essential for the maturation of mRNA and is also RNA-dependent.

3. **Conclusion**:
- Since all three processes (metabolism, translation, and splicing) involve RNA and are essential life processes, the correct answer is **Option D: All of these**.

### Final Answer:
The essential life processes that evolved around RNA are **all of these** (metabolism, translation, and splicing).
