Which process involves synthesizing RNA from a DNA template?

• A. Translation
• B. Transcription
• C. Replication
• D. Translocation

Answer: (B)

The correct process for synthesizing RNA from a DNA template is transcription. During transcription, the enzyme RNA polymerase binds to a specific region of the DNA and unwinds the DNA helix. It then uses one strand of the DNA as a template to build a complementary RNA molecule. This RNA molecule is synthesized in the 5' to 3' direction and is a crucial step in gene expression, ultimately leading to the production of proteins.

This process is distinct from translation, which is the phase where messenger RNA (mRNA) is decoded by ribosomes to produce polypeptides (proteins). Replication refers to the process of duplicating the entire DNA molecule prior to cell division, ensuring that each daughter cell receives an identical set of genetic information. Lastly, translocation generally refers to the movement of molecules, such as the movement of ribosomes along mRNA during translation, rather than the synthesis of RNA from DNA. Therefore, transcription is the defining process that specifically involves the formation of RNA from a DNA template.
