Identify the incorrect statement:

Options

A. According to central dogma in molecular biology, the flow of genetic information is unidirectional from DNA to RNA (transcription).
B. The central dogma of molecular biology was given by Temin and Baltimore.
C. Ribonucleic acid (RNA) was the first ge netic material that was discovered.
D. It was discovered through several researches that the essential life processes such as metabolism, translation, splicing, etc., evolved around RNA.

Explanation

To solve the question of identifying the incorrect statement, we will analyze each of the provided statements step by step.

### Step 1: Analyze the First Statement
- **Statement:** According to Central Dogma in Molecular Biology, the flow of genetic information is unidirectional from DNA to RNA, and this process is called transcription.
- **Analysis:** This statement is correct. The Central Dogma describes the flow of genetic information from DNA to RNA (transcription) and from RNA to proteins (translation).

### Step 2: Analyze the Second Statement
- **Statement:** The Central Dogma of Molecular Biology was given by Tamin and Baltimore.
- **Analysis:** This statement is incorrect. The Central Dogma was first articulated by Francis Crick in 1957, and it was published in 1958. Tamin and Baltimore are known for their work on reverse transcription in retroviruses, not for the Central Dogma itself.

### Step 3: Analyze the Third Statement
- **Statement:** Ribonucleic acid (RNA) was the first genetic material that was discovered.
- **Analysis:** This statement is correct. RNA was indeed found to be the first genetic material in several studies, and it plays a crucial role in various life processes.

### Step 4: Conclusion
- After analyzing all the statements, we conclude that the second statement is incorrect.

### Final Answer
The incorrect statement is: **The Central Dogma of Molecular Biology was given by Tamin and Baltimore.**
