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.
What is Fiber Optic Pigtail. fiber-optic-pigtails. Fiber optic pigtail is a fiber cable end with fiber optic connectors at only either side of the cable while leaving sleep issues no connectors, so the connector side could be from the equipment and the other part can be melted with optical cable fibers.he end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber within the trunk breaks out the multi-fiber cable into its component fibers for connection to the end equipment. Fiber pigtails can have female or male connectors.
