Translation expression/regulation Protein

Nuclear receptors (steroid receptors) that, when bound to their specific ligand (such as the hormone estrogen), alter the rate at which specific genes are transcribed and translated into cellular proteins. Because steroid hormones function through mechanisms intimately related to the regulation of gene expression, we consider them here only briefly (Section 12.8) and defer a detailed discussion of their action until Chapter 28. 

FIGURE 6.3 An overview of gene expression. A gene is typically regulated by an upstream promoter through the action of transcription factors, resulting in the synthesis of an mRNA from the DNA template in a process known as transcription. This mRNA will later on get translated into a protein through the action of ribosomes.
