Other genes are only active in certain cells. An amino acid e. Intro To Gene Expression Central Dogma Article Khan Academy Nutrient A binds to a repressor protein which when bound to nutrient A represses the expression of the genes involved in this biosynthetic pathway. . It is the flow of information from DNA to RNA with enzymes help and the end product is proteins and other biochemical molecules. Denaturing of proteins leads to loss of function i. Among these are formation of female germ cells initiation and completion of meiosis and establishment of a maternal store of materials to support. Their expression is regulated by a variety of mechanisms. Without the repressor these genes are transcribed. A gene is a genomic sequence either DNA or RNA that has all the elements necessary to direct and encode the expression of functional products either RNA or protein Messenger RNA mRNA. The Nutrient A pathway is...
