Gene Expression and Genetic Engineering

The process by which genetic instructions are utilised to create gene products is known as gene expression. These are typically proteins, which go on to serve important roles as receptors, hormones, and enzymes. Therefore, a cell's capabilities are determined by the hundreds of genes that are expressed in that cell. Furthermore, the cell has the potential to regulate itself by controlling the quantity and kind of proteins it produces at each stage of the information flow from DNA to RNA to protein.

The term "genetic engineering" refers to the direct modification of DNA to change an organism's characteristics in a specific way. The process of manually introducing additional DNA into an organism is known as genetic engineering. The objective is to enhance one or more novel features.
