Hello! needing assistants :p would be well appreciated like alot. *brainlest included *

Finn listed two of the three steps involved in gene therapy. 1. The normal allele is removed from the chromosome. 2. The normal allele is added to the cells of a person with the disorder.

Which step should he also include, and where?

a) The normal allele is copied before step 1.
b) The normal allele is copied after step 1.
c) The unhealthy gene is cut from the DNA before step 2.
d) The unhealthy gene is cut from the DNA after step 2.d

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
