An intron is any nucleotide sequence within a gene that is removed by RNA splicing during maturation of the final RNA product. The term intron refers to both the DNA sequence within a gene and the corresponding sequence in RNA transcripts. Sequences that are joined together in the final mature RNA after RNA splicing are exons. Introns are found in the genes of most organisms and many viruses, and can be located in a wide range of genes, including those that generate proteins, ribosomal RNA (rRNA), and transfer RNA (tRNA). When proteins are generated from intron-containing genes, RNA splicing takes place as part of the RNA processing pathway that follows transcription and precedes translation.
The word intron is derived from the term intragenic region, i.e. a region inside a gene. Although introns are sometimes called intervening sequences, the term "intervening sequence" can refer to any of several families of internal nucleic acid sequences that are not present in the final gene product, including inteins, untranslated sequences (UTR), and nucleotides removed by RNA editing, in addition to introns.

Introns are removed from eukaryotic RNA transcripts and exons are spliced together. This video shows the details of the process of removal of a typical nuclear intron, including the roles of the various SNRNPs. Includes the formation of the A, B, and C complexes, and the two transesterification reactions.

Hear my prayer,
Hear my prayer,
Hear my prayer,
Everybody, hear my prayer.
I want to see the Prince of Peace
Lookin' out for me.
I want to see the Prince of Peace
Lookin' out over me.
I want to hear the bells of peace
Ringin' out for me.

I want to hear a song of peace
Singin' out for me.
I want to hear a song of peace
Singin' out just for me.

Lookin' out for me.
I want to see the Prince of Peace
Lookin' out just for me.
