Exon part of m-RNAs have code for : -Eukaryotic genes are split genes. The coding sequences are called exons and the non-coding intervening sequences are called introns.
During RNA processing (splicing), the introns are removed and the exons are joined to form the mature mRNA.
The exons carry the codons that are translated into the amino acid sequence of a protein (polypeptide).
So the exon part of mRNA codes for protein.
