Describe gene cloning and the polymerase chain reaction?

The RNA travels down the DNA strand adding the genetic code

My bio class just went over this today haha
gene cloning is made up of 4 steps: isolation, ligation, transformation, and selection. generally, a gene is isolated, forms recombinant DNA, which is then put into an organism. 
the polymerase chain reaction, on the other hand, has 3 steps: denaturing, annealing, and extension. DNA is first heated to break bonds between the strands, then cooled and mixed with smaller DNA strands called primers. :)

It feels feed the echo system
