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.
This is to ensure that in the event of a fire, plenum rated armored fiber optic cable generates low smoke, preventing the spread of smoke and fire. The Armored Fiber Optic Cable, Multimode, 62.5/125 OM1, Plenum is manufactured of Corning glass and is suitable for both indoor and outdoor applications.
