Explicación
## Step 1The first question is about the initial step a scientist would take when analyzing a small sample of DNA. The options provided are:a. Using restriction enzymes to make multiple copies of the DNA.b. Using the polymerase chain reaction (PCR) to make multiple copies of the DNA.c. Transferring the DNA into bacteria, and allowing the bacteria to be replicated many times.d. Using restriction enzymes to cut the DNA into many small pieces.## Step 2The Polymerase Chain Reaction (PCR) is a technique used to amplify a small sample of DNA, creating millions to billions of copies. This is the most direct and efficient way to analyze a small sample of DNA.## Step 3The second question is about the potential outcomes of applying recombinant DNA technology. The options provided are:a. Changes to the roles of DNA and RNA in protein synthesis.b. Changes to the genetic code as it is used by a living organism.c. Changes to the genetic composition of a living organism.d. Changes to the percentage of DNA that is replicated by a living organism.## Step 4Recombinant DNA technology involves the manipulation of an organism's genes using biotechnology. It is used to alter the genetic makeup of an organism, which can lead to changes in the organism's traits.
