What is regulation of gene expression?
Regulation of Gene Expression 1 Define the term regulation as it applies to genes. For a cell to function properly, necessary proteins must be synthesized at the proper time. 2 Expression of Genes. For a cell to function properly, necessary proteins must be synthesized at the proper time. 3 Prokaryotic and Eukaryotic Gene Regulation.
What is the process of gene expression?
In Summary: Expression of Genes. Gene 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.
How are genes regulated in a cell?
Define the term regulation as it applies to genes For a cell to function properly, necessary proteins must be synthesized at the proper time. All cells control or regulate the synthesis of proteins from information encoded in their DNA. The process of turning on a gene to produce RNA and protein is called gene expression.
Why is gene regulation important in cancer?
The control of gene expression is extremely complex. Malfunctions in this process are detrimental to the cell and can lead to the development of many diseases, including cancer. Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on” (expressed).
Regulation of Gene Expression (cont) ~ the expression of different genes by cells with the same genome DNA Packing chromatin: a complex of DNA and protein histones: proteins associated with DNA packing DNA methylation “off switch” tightly wrapped around histones genes can not be transcribed methyl groups are added to the DNA

What is gene expression in a cell?
The process of turning on a gene to produce RNA and protein is called gene expression. Whether in a simple unicellular organism or a complex multi-cellular organism, each cell controls when and how its genes are expressed.
How do prokaryotic cells regulate gene expression?
Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes.
