1
Understand the role of helicase enzymes: Helicase enzymes are responsible for unwinding the DNA double helix at the origin of replication, allowing the replication machinery to access the DNA strands.
Identify the number of origins of replication: The problem states that there are 5 origins of replication on the DNA strand.
Determine the number of helicase enzymes needed per origin: Typically, each origin of replication requires two helicase enzymes, one for each direction of unwinding the DNA.
Calculate the total number of helicase enzymes: Multiply the number of origins of replication (5) by the number of helicase enzymes needed per origin (2).
Conclude the calculation: The total number of helicase enzymes required is the product of the number of origins and the helicase enzymes per origin.
