What process involves the synthesis of RNA from a DNA template?

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

Answer: (C)

The process that involves the synthesis of RNA from a DNA template is known as transcription. During transcription, a specific segment of DNA is copied into messenger RNA (mRNA) by the enzyme RNA polymerase. This process is fundamental in gene expression, as it allows the genetic information encoded in DNA to be translated into a functional product, primarily proteins. In transcription, the DNA double helix unwinds, and one of the strands serves as a template for the synthesis of the complementary RNA strand. The resulting mRNA undergoes further processing before it can be translated into a protein. This includes the addition of a 5' cap and a poly-A tail, as well as splicing to remove non-coding regions (introns) and join together the coding sequences (exons). Understanding transcription is key to grasping how genes are expressed and regulated within the cell, laying the groundwork for cellular functions, development, and responses to environmental stimuli.
