Exons and introns are segments of DNA or RNA within a gene where exons code for proteins, while introns are non-coding sequences removed during RNA splicing. This process is essential for producing functional mRNA, allowing for the expression of genes in eukaryotic organisms.

Coding for proteins

Non-coding sequences

RNA splicing is a critical process in eukaryotic gene expression where introns are removed from pre-mRNA and exons are joined to form mature mRNA. This process allows for the generation of multiple protein isoforms from a single gene through alternative splicing, contributing to proteomic diversity.

Expression of genes

Eukaryotic organisms are characterized by cells that contain a nucleus and other membrane-bound organelles, distinguishing them from prokaryotic organisms. This cellular complexity allows for greater specialization and the development of multicellular organisms, including plants, animals, and fungi.
