Science / Genetics / Exons: Portion of a gene included in the transcript of a gene and survives processing of the rna in the cell nucleus to become part of a spliced messenger of a structural rna in the cell cytoplasm: an exon specifies the amino acid sequence of a portion of the complete polypeptide.


Science / Genetics / Introns: The dna base sequences interrupting the protein- coding sequences of a gene: these sequences are transcribed into rna but are cut out of the message before it is translated into protein. Compare exons MORE

Science / Genetics / Alternative Splicing: Different ways of combining a gene's exons to make variants of the complete protein MORE


Science / Biology / Exon: The DNA bases that code for an amino acid sequence. Exons are separated by introns that code for no amino acid sequences. MORE
