DNA extraction from water samples was conducted randomly to minimize the possible biases from contamination during laboratory workflow. Contamination control WebThe process involves three steps – initiation, elongation and termination. DNA helicase and single-strand binding proteins are responsible for unwinding and stabilization. The replication process is halted as the leading strand of one replication bubble meets the lagging strand of another replication bubble.
