First DNA helicase unwinds the strand of DNA. Then, DNA polymerase binds to the anti-sense strand of the DNA and adds RNA nucleotides in a sequence complementary to the strand of DNA. The DNA polymerase c...

We know from simple fraction rules that dy/dx=(dy/dt)/(dx/dt). dy/dt=2t, dx/dt=3t^2+1. Therefore, dy/dx=2x2/12+1=4/13
