Global regulation often occurs when cells are under stress and translation would waste energy or be harmful. A protein kinase called mTor is the major player in this method.  As a kinase it adds and removes phosphates from other molecules.  When the cell/organims is stressed, the mTor is inactivated.  It therefore doesn’t add phosphates to translation initiation factors and so they are inactive and translation stops.What happens when the cell/organims is NOT stressed?

Genomics

Genes are responsible for transmitting the characters located on the chromosomes from one individual to another across the generations. Genetics is the study of different genes that are involved in different functions. Genetics is a branch of biology that studies genes, genetic diversity, and heredity in living organisms. The genetic system consists of genetic notations, which is a system of signs and symbols. Genotype refers to the organism's genetic composition, and phenotype refers to the observable property of the organism.
