How are genes regulated in eukaryotes
WebThe answer lies in the difference in gene expression and regulation used. It is estimated that the human genome encodes approximately 25,000 genes, about the same number as that for corn and ... WebDiscuss the role of transcription factors in gene regulation. Like prokaryotic cells, the transcription of genes in eukaryotes requires the action of an RNA polymerase to bind to a DNA sequence upstream of a gene in order to initiate transcription. However, unlike prokaryotic cells, the eukaryotic RNA polymerase requires other proteins, or ...

WebUp-regulated expression of genes in mammals can be initiated when signals are transmitted to the promoters associated with the genes. Cis-regulatory DNA sequences that are located in DNA regions distant from the promoters of genes can have very large effects on gene expression, with some genes undergoing up to 100-fold increased expression …
