‘Junk DNA’: Age of Intron - Front Line Genomics

WebScientists once thought noncoding DNA was “junk,” with no known purpose. However, it is becoming clear that at least some of it is integral to the function of cells, particularly the control of gene activity. For example, noncoding DNA contains sequences that act as regulatory elements, determining when and where genes are turned on and off. WebThe human genome is thought to contain about how many genes? 20,000 to 25,000 Why might the number of genes in the genome underestimate the number of different proteins that an organism makes? many genes undergo alternative splicing, so that different proteins with different exon combinations are produced form the same gene
