Steroid hormones are derived from cholesterol. There are varios steriod hormone present inside our body such as Testosterone,glucocorticoid, mineralocortocoid, coticosterone etc.
Steroid hormone are hydrophobic in nature as a result they can cross the plasma membrane and binds to the receptor present in either nucleus or cytoplasm.
After binding to the rceceptor the receptor hormone complex interract with specific DNA sequence known as steroid hormone responsive element which further leads to the transcription of that DNA resulting in the formtion of mRNA that further enters into the translation process to synthesize specific protein associated with the functioning of that hormone .
Copper is a good conductor of electricity and this is why it is used in electrical equipment to transmit electrons with the least resistance. Cable conductors are made of copper and used to transmit data. Copper is now being replaced by optic fiber that is made of glass. Instead of using electrons, fiber optic transmits data using photons – which transmits more data rate than copper.
