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.
Diagram showing at which stages in the DNA-mRNA-protein pathway expression can be controlled. Gene expression is the process by which the heritable information in a gene, the sequence of DNA base pairs, is made into a functional gene product, such as protein or RNA. The basic idea is that DNA is transcribed into RNA, which is then translated into proteins. Proteins make many of the structures and all the enzymes in a cell or organism. Several steps in the gene expression process may be modulated (tuned).
