FILL IN THE BLANKS The difference between introns and exons are . The reasons introns exist is because

Introns and exons are nucleotide sequences within a gene. Introns are removed by RNA splicing as RNA matures, meaning that they are not expressed in the final messenger RNA (mRNA) product, while exons go on to be covalently bonded to one another in order to create mature mRNA.

Explanation:

could of just searched it up

a) nucleotide sequences within a gene.

b) the protein repertoire or variety is greatly enhanced by alternative splicing in which introns take partly important roles.
