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.
The 3M 2178 Fiber Optic Splice Case is used in underground, aerial, building entrance, and pedestal. applications. The splice case has two cable entrance ports on each end. Port plugs allow the case to be. used for butt or inline splices. The rigid nonfilled case provides moisture protection and can be pressurized. The integral organizer and splicing trays accommodate single-mode and multi-mode fiber optic field splices.
