  • RNA formed at the transcription to direct protein synthesis in the cytoplasm

    Messenger RNA (mRNA)

    • Means "copying" or "rewriting"

    • The encoding of genetic information on a strand of mRNA

    • begins with an enzyme RNA polymerase (may use (A)denine, (G)canine, (C)ytosine, or (U)racial; but never (T)hymine

    Transcription

  • A sequence of three nitrogenous bases along an mRNA strand that will specify the location of a single amino acid in a peptide chain

    Codon

    • The process of peptide formation from the instructions carried by a mRNA strand

    Translation

    • Molecules of a third form of RNA

    • delivers amino acids (ATGCU) that will be used by the ribosome to assemble a protein

    Transfer RNA (tRNA)

  • Each tRNA molecule contains a triplet of nitrogenous bases called...

    • It's complementary to a specific codon on the mRNA and will bind to it.
