Which one is correctly matched ?

Options

A. Oncogenes -Ageing
B. Initiation factors-Amino acid activation
C. Replication fork -mRNA
D. AIDS virus-Reverse transcriptase

Answer

To determine which option is correctly matched, let's analyze each option step by step:

### Step 1: Analyze the first option - Oncogen and Aging
- **Oncogen**: These are genes that have the potential to cause cancer. They are not related to the aging process.
- **Conclusion**: This option is **incorrectly matched**.

### Step 2: Analyze the second option - Initiation Factor and Amino Acid Activation
- **Initiation Factors**: These are proteins that play a crucial role in the initiation of translation, which is the process of synthesizing proteins from mRNA.
- **Amino Acid Activation**: This refers to the process of attaching amino acids to their corresponding tRNA molecules, which is a separate step in protein synthesis.
- **Conclusion**: This option is **incorrectly matched**.

### Step 3: Analyze the third option - Replication Fork and mRNA
- **Replication Fork**: This is the area where DNA replication occurs, not where mRNA is synthesized.
- **mRNA**: This is produced during the transcription process, which is separate from DNA replication.
- **Conclusion**: This option is **incorrectly matched**.

### Step 4: Analyze the fourth option - AIDS Virus and Reverse Transcriptase
- **AIDS Virus (HIV)**: HIV (Human Immunodeficiency Virus) is known to be a retrovirus that contains reverse transcriptase.
- **Reverse Transcriptase**: This enzyme allows the virus to convert its RNA genome into DNA, which can then integrate into the host's genome.
- **Conclusion**: This option is **correctly matched**.

### Final Answer
The correctly matched option is **AIDS Virus and Reverse Transcriptase**.
