Copying genetic information from one strand of DNA into RNA is :

Options

A. Translation
B. Transcription
C. Transformation
D. Transduction

Answer

To answer the question "Copying genetic information from one strand of DNA into RNA is:", we will analyze the options provided and identify the correct process involved in this transformation.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the process of copying genetic information from DNA to RNA. This is a fundamental concept in molecular biology.

2. **Analyzing the Options**:
- **Option 1: Translation**: This process involves the conversion of messenger RNA (mRNA) into a protein. It does not involve copying from DNA to RNA, so this option is incorrect.

- **Option 2: Transcription**: This process involves the synthesis of RNA from a DNA template. During transcription, the DNA strands are separated, and one strand serves as a template for the formation of RNA. This is the correct process we are looking for.

- **Option 3: Transformation**: This refers to the process of introducing foreign DNA into an organism, typically used in genetic engineering. It does not pertain to the copying of DNA into RNA, making this option incorrect.

- **Option 4: Transduction**: This process involves the introduction of foreign DNA into a cell via a viral vector. Similar to transformation, it does not involve the copying of DNA into RNA, so this option is also incorrect.

3. **Identifying the Correct Answer**: Based on the analysis, the correct answer is **Option 2: Transcription**. This is the process where genetic information is copied from DNA to RNA.

### Final Answer:
The process of copying genetic information from one strand of DNA into RNA is called **Transcription**.
