Exon (Noun)
Meaning
Sequence of a gene's DNA that transcribes into protein structures; "exons are interspersed with introns".
Classification
Nouns denoting substances.
Examples
- The human gene sequence revealed several distinct exons interspersed with noncoding intron sequences.
- Gene editing techniques allowed researchers to manipulate and alter specific exons within the gene.
- Exons are the coding regions of a gene that are transcribed into a mature protein product after the removal of introns.
- Following transcription and splicing, the resulting mRNA is composed of the rearranged exons from the original gene sequence.
- Mutations in critical exons can sometimes result in premature stop codons and nonfunctional or truncated protein products.
