From the sequencing of the human genome, we believe that there are approximately 21,000 protein-coding genes in the genome, of which 1500-3000 are transcription factors.If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns?
Differential Controls
Devices that function based on the difference in variables (such as temperature, pressure, or flow rate) to adjust or maintain system operation.
Mechanical Holding Circuit
A circuit design that maintains the current flow or signal, keeping a device like a relay activated even after the initial actuating signal is removed.
Motor Control Circuits
Electrical circuits designed to control the start, stop, speed, and direction of an electric motor.
Motor Starter
A device that controls the use of electrical power to equipment, specifically to an electric motor, by means of protection and control circuitry.
