Preliminary Messenger RNA
Precursor mRNA (pre-mRNA) is an immature single strand of messenger ribonucleic acid (mRNA). pre-mRNA is synthesized from a DNA template in the cell nucleus by transcription. Pre-mRNA comprises the bulk of heterogeneous nuclear RNA (hnRNA). The term hnRNA is often used as a synonym for pre-mRNA, although, in the strict sense, hnRNA may include nuclear RNA transcripts that do not end up as cytoplasmic mRNA.
Once pre-mRNA has been completely processed, it is termed "mature messenger RNA", "mature mRNA", or simply "mRNA".

Famous quotes containing the words preliminary and/or messenger:
“Religion is the state of being grasped by an ultimate concern, a concern which qualifies all other concerns as preliminary and which itself contains the answer to the question of a meaning of our life.”
—Paul Tillich (1886–1965)
“O you singers solitary, singing by yourself, projecting me,
O solitary me listening, never more shall I cease perpetuating you
Never more shall I escape, never more the reverberations,
Never more the cries of unsatisfied love be absent from me,
Never again leave me to be the peaceful child I was before what
there in the night,
By the sea under the yellow and sagging moon,
The messenger there aroused, the fire, the sweet hell within,
The unknown want, the destiny of me.”
—Walt Whitman (1819–1892)
