DNA Gene Sequence - Exons and Introns
This section provides a quick introduction of the Genetic Translation process, which is the process of translating the nucleotide sequence of a mRNA (Messenger RNA) into the amino acid sequence linked with peptide bonds to build a new protein according to the genome codon map chart.
A gene stored in a DNA actually has two types of segments:
The diagram (source: biotechprimer.com) below shows how introns are removed during the alternative splicing step:
Here is a list of multiples of exons and introns representing a full genomic DNA sequence, which is mapped to its coding DNA (or mRNA) sequence, and its protein sequence.
