The stretch of DNA that is transcribed into an RNA molecule is called transcription unit. Transcription has some proofreading mechanisms, but they are fewer and less effective than the controls for DNA; therefore, transcription has a lower copying fidelity than DNA replication.ut to answer your question to the point, only one strand of DNA is copied during transcription for practical reasons. The one strand that is copied will result to a duplicate copy of the other strand that WAS NOT copied.
Breakout Cable A type of Fiber optic Cable containing several fibers, each with its own Jacket and all of them surrounded by one common jacket. Breakout cables are designed for convenient installation of Fiber Optic Connectors but tend to have high Transmission losses due to bends in the fibers.
Although fiber optic functions through the use of a cable, the contents inside the cable are what differentiate it from cable Internet. Fiber optic consists of glass cables which is the reason it is also referred to as an optical cable.epending upon the type of glass that is used during cable construction, the speed of the connection may fluctuate, but still produces a very fast connection speed. The typical speed for a fiber optic Internet connection will range between 150 Mbps (megabits per second) and 500 Mbps.
