#Introns and #exons are terms used in the context of gene expression and the structure of eukaryotic genes. Here's a brief explanation:

Introns:

#Introns are #non-coding regions within a gene's #DNA sequence.
They are removed from the pre-mRNA (precursor messenger RNA) during a process called "splicing."
Introns do not contribute to the final protein sequence, as they are not included in the mature mRNA (messenger RNA) that is translated into protein

Exons are the coding regions within a gene's DNA sequence.
They are the segments of the gene that are retained in the mature mRNA and are ultimately translated into the final protein sequence.
Exons contain the information necessary for the synthesis of the protein, as they encode the amino acid sequence of the protein.
During the process of transcription, the entire gene, including both introns and exons, is initially transcribed into a pre-mRNA.
During the subsequent process of splicing, the introns are removed, and the exons are joined together to form the mature mRNA.
