Why do helicase and gyrase need to work together? correct answers Helicase unwinds DNA and gyrase relieves the torsional strain. Match the name of the DNA repair mechanism with the correct description. Functions with DNA replication to remove incorrect nucleotides from the nascent strand. Requires an endonuclease to remove an abasic nucleotide before DNA Pol I can replace a portion of the strand. Is needed to repair chemical damage in DNA effecting more than one nucleotide, such as c...

Progression: Construction Coordinator I - II Exam Answered Correctly. A chain trencher A return path sweep-and-alignment system is used to adjust which of the following? Anomalies, such as echoes and blind spots, can hide cable faults or cause a technician to misinterpret the signature of a time domain reflectometer (TDR) waveform. What causes an echo on a waveform TDR? As the RF signal travels on the coaxial cable, one portion of the signal may be attenuated more than the others. ...
