Answer: 
The answer is 'D'. Transcription is the process by which a single stranded mRNA is formed from the double stranded DNA. 
Explanation:
The central machinery of biology involves three processes- replication, transcription and translation. The process by which DNA doubles itself is called <u>replication</u>. In translation, protein is formed from the messenger RNA or mRNA. The major steps involved in transcription are:
- <em>Initiation</em>
- <em>Elongation</em>
- <em>Termination</em>
In the process of translation, amino acids bind together in the <u>ribosome</u> to form a polypeptide chain.
