WebA typical animal genome encodes approximately 20,000 genes. However, not all genes are expressed in all cell types and gene expression often changes drastically over time, such as during embryonic development. Adding further complexity is that the control of gene expression can occur at multiple steps: accessibility of a gene to activating transcription … Webregulate gene expression in eukaryotic organisms. Gene regulation allows for increasing organism complexity. It’s also efficient: only those genes required by the cell are expressed.
