Genes and introns in prokaryotic cells

WebGene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. The set of genes expressed in a cell determines the set of proteins and ... WebIn genes that lack introns (e.g. most prokaryotic genes), an ORF in the DNA sequence will define the entire translated region. If splicing occurs (i.e. in genes with introns), a final processed mRNA (transcript from a protein coding gene) will have a long ORF that directs ribosomes to produce a polypeptide.
