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.
Fiber Optics is the communications medium that works by sending optical signals down hair-thin strands of extremely pure glass or plastic fiber. The light is guided down the center of the fiber called the core.he core is surrounded by a optical material called the cladding that traps the light in the core using an optical technique called total internal reflection.. The fiber itself is coated by a buffer as it is made to protect the fiber from moisture and physical damage.
