WebAll 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. Whether in a simple unicellular organism or a complex multi-cellular organism, each cell controls when and how its genes are expressed. WebGene therapy and genetic engineering are two closely related technologies. Gene therapy seeks to alter genes to correct genetic defects and thus prevent or cure genetic diseases. …

WebDiagram illustrating what an operon is. At the top of the diagram, we see a bacterial cell with a circular bacterial chromosome inside it. We zoom in on a small segment of the chromosome and see that it is an operon. The DNA of the operon contains three genes, Gene 1, Gene 2, and Gene 3, which are found in a row in the DNA. WebDec 18, 2016 · In plants that get water, you may be able to see the difference between a plant with a tall allele and a plant with a short allele. Plants that do not get enough water will undoubtedly be stunted and grow much less than they could if they had water. This is just one simple example of how the environment can change the phenotype of an organism.

WebThese different patterns of gene expression cause your various cell types to have different sets of proteins, making each cell type uniquely specialized to do its job.
