A scientist examines a diagram of mRNA during a biology lecture.

Definition
  1. Noun:
    • The template for protein synthesis: mRNA is a form of ribonucleic acid (RNA) that serves as an intermediary, carrying genetic instructions copied from DNA.
    • The form of RNA that carries information: It specifically transfers the coded information from the DNA in the cell's nucleus to the ribosomes in the cytoplasm, where proteins are synthesized.
Usage Examples
  • Noun:
    • Scientists studied the mRNA to understand how the gene is expressed.
    • The vaccine uses synthetic mRNA to instruct cells to produce a viral protein.
    • During transcription, mRNA is formed using a DNA template.
Advanced Usage
  • "mRNA transcript": Refers to the specific RNA molecule produced from a DNA segment during transcription.
    • The stability of the mRNA transcript affects protein levels.
  • "mRNA sequence": Refers to the specific order of nucleotide bases in the mRNA molecule.
    • Researchers analyzed the mRNA sequence to identify mutations.
  • "mRNA vaccine": A type of vaccine that uses a synthesized strand of mRNA to teach cells how to make a protein that triggers an immune response.
    • The development of mRNA vaccines represented a significant technological advance.
Variants and Related Words
  • Messenger RNA: The full term for mRNA.
  • RNA (Ribonucleic Acid): The broader category of nucleic acids to which mRNA belongs. Other types include tRNA (transfer RNA) and rRNA (ribosomal RNA).
  • Transcription: The process of synthesizing mRNA from DNA.
  • Translation: The process of synthesizing a protein from the mRNA template at a ribosome.
Synonyms
  • Messenger RNA: The direct synonym and full name.
  • Transcript: In a genetic context, this can refer to the RNA product of transcription.
Related Phrases and Compounds
  • mRNA degradation: The natural breakdown of mRNA molecules in the cell.
  • mRNA cap: A modified nucleotide added to the start of an mRNA molecule that is important for stability and translation.
  • Poly-A tail: A sequence of adenine nucleotides added to the end of mRNA, influencing its stability and export from the nucleus.
