Eukaryotic Gene Structure
Eukaryotic genes are segments of DNA that carry instructions for building proteins. They consist of coding regions called exons, which directly determine the protein's structure, and non-coding regions called introns, which are removed before the gene is used. The entire gene is flanked by regulatory sequences that control when and where the gene is active. This complex structure allows for precise regulation and splicing, enabling cells to produce different proteins from the same gene through processes like alternative splicing. Overall, eukaryotic genes are organized units that balance coding instructions with regulation to ensure proper cell function.
