splicing splic·ing (splī'sĭng)
n.
Gene-splicing.
The removal of introns and the joining of exons from mRNA precursors. Also called RNA splicing.
| splice (splīs) Pronunciation Key
To join together genes or gene fragments or insert them into a cell or other structure, such as a virus, by means of enzymes. In genetic engineering, scientists splice together genetic material to produce new genes or to alter a genetic structure. In messenger RNA, the introns are removed, and exons are spliced together to yield the final messenger RNA that is translated. See also exon, intron. |
