Which of the following process is involved in conversion of DNA to RNA:
**Core Concept**
The conversion of DNA to RNA is a fundamental process in molecular biology, where DNA is transcribed into a complementary RNA molecule. This process is crucial for protein synthesis, as it allows the genetic information encoded in DNA to be expressed in the form of RNA.
**Why the Correct Answer is Right**
The correct process involved in conversion of DNA to RNA is transcription. During transcription, an enzyme called RNA polymerase reads the template DNA strand and matches the incoming nucleotides to the base pairing rules (A-T and G-C). This results in the synthesis of a complementary RNA molecule, which is complementary to the DNA template. The RNA molecule is then processed to remove any introns and add a 5' cap and poly-A tail.
**Why Each Wrong Option is Incorrect**
**Option A:** Translation is the process of converting RNA into protein, not DNA to RNA.
**Option B:** DNA replication is the process of making an exact copy of DNA, not converting DNA to RNA.
**Option C:** DNA repair is the process of fixing damaged DNA, not converting DNA to RNA.
**Clinical Pearl / High-Yield Fact**
Remember the acronym "TRASH" to help you remember the basic steps of transcription: Template (DNA), Recognition (RNA polymerase binding), Activation (initiation of transcription), Synthesis (RNA synthesis), and Helicase ( unwinding of DNA).
**Correct Answer: C. Transcription. The process of converting DNA to RNA.**
