Which job must enzymes do before replication can begin? identify one origin for replication sequence the leading dna strand unwind part of the original dna molecule determine one direction for replication

Unwinding part of original DNA

Explanation:

For DNA to be replicated, it has to be unwound. This allows the original DNA strands to be used as a template for a copy by the replicating enzymes-DNA polymerase. Helicases are responsible for this unwinding following which a replication fork is formed.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
