Introns are non-coding sequences found within genes that are removed during the process of RNA splicing, allowing for the creation of a mature mRNA molecule that can be translated into protein. This mechanism enables a single gene to produce multiple proteins through alternative splicing, significantly increasing the diversity of proteins an organism can produce.

Intron

Introns are non-coding sequences within a gene that are transcribed into RNA but are removed during RNA splicing before translation into protein. They play crucial roles in gene expression regulation and alternative splicing, contributing to protein diversity and evolution.

Non-coding sequences

Genes are the fundamental units of heredity, composed of DNA sequences that encode the instructions for building and maintaining an organism. They play a crucial role in determining physical traits, influencing behaviors, and contributing to the risk of developing certain diseases.

Genes

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.

RNA Splicing

Mature mRNA molecule

Translated into protein

Alternative splicing is a post-transcriptional process allowing a single gene to produce multiple protein isoforms by varying the inclusion or exclusion of specific exons. This mechanism significantly increases proteomic diversity and plays a crucial role in regulating gene expression and cellular function in eukaryotic organisms.

Alternative Splicing

Diversity of proteins

An organism is a living entity that can carry out life processes independently, ranging from single-celled bacteria to complex multicellular humans. Organisms interact with their environment and other organisms, playing a crucial role in ecosystems and the biosphere as a whole.
