About 50% proportion of exons in primary transcripts leave the nucleus of a eukaryotic cell.
A gene's exons are the regions that code for proteins. Exons are mRNA coding regions where amino acids are codified. Numerous exons encode various protein domains. The domains can be encoded by a single exon or by several exons joined together. A portion of the genome that is contained within an mRNA molecule is known as an exon. Exons can be classified as "coding" or "non-coding," depending on whether they contain the instructions needed to make a protein. Exons and introns make up each gene in the genome.
Eukaryotic creatures are big and complicated because eukaryotic cells include nuclei that are encased in nuclear membranes. Eukaryotic cells are found in protozoa, fungi, plants, and mammals. They fall under the Eukaryotic kingdom. Plants, mammals, fungi, and protists all contain eukaryotic cells.
