Overview
Non-coding DNA, which includes introns and regulatory sequences, plays a vital role in the regulation of gene expression and the overall functioning of cells. While introns are often seen as non-essential, they contribute to the complexity of gene regulation through mechanisms like alternative splic...
Key Terms
Example: In eukaryotic genes, introns are spliced out to produce mature mRNA.
Example: Exons are expressed in the final protein product.
Example: Promoters and enhancers are types of regulatory sequences.
Example: MicroRNAs are a type of non-coding RNA that regulate gene expression.
Example: Splicing is essential for generating functional mRNA.
Example: Gene expression can be influenced by regulatory sequences.
