What type of RNA carries instructions from DNA to the ribosome?

• A. tRNA
• B. rRNA
• C. mRNA
• D. cRNA

Answer: (C)

mRNA, or messenger RNA, is the type of RNA that carries genetic instructions from DNA to the ribosome, where proteins are synthesized. This process is essential for gene expression and occurs in two main steps: transcription and translation. During transcription, the DNA sequence of a gene is transcribed into a complementary RNA sequence, producing mRNA. This mRNA then exits the nucleus and enters the cytoplasm, where it serves as a template for the ribosome during protein synthesis. The primary function of mRNA is to serve as an intermediary that conveys the genetic information needed for the synthesis of proteins, which are crucial for various cellular functions. This makes mRNA a fundamental component in the flow of genetic information within a cell, from DNA to functional proteins.
