For me, anything that contains casein, the protein found in milk, is considered a dairy item to be avoided. This includes cow's milk, butter, cheeses, and ice cream. This is not to be confused with lactose intolerance, which is an inability to digest lactose, the sugar found in milk and milk products.
In genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype, i.e. observable trait. The genetic code stored in DNA is interpreted by gene expression, and the properties of the expression give rise to the organism's phenotype.deally measurement of expression is done by detecting the final gene product (for many genes this is the protein) however it is often easier to detect one of the precursors, typically mRNA, and infer gene expression level.
Definition of Gene Expression. A gene is a small piece of genetic material written in a code and called DNA. Each gene has within it a set of instructions for making molecules that organisms need to survive. Genes themselves cannot be used by an organism.Instead they must be turned into a gene product.n important component that is always present is RNA polymerase. This is the machine that actually reads the DNA code and makes the RNA. Transcription factors that promote gene expression are called activators. Figure 1 shows transcription factors and RNA polymerase (RNAP) making an mRNA copy of the DNA.
