How do scientists make clones?

Answer 1

The first step in using the polmerase chain reaction method to copy a gene is to heat a piece of DNA which separates its two strands. Then, as the DNA cools, primers bind to the single strands. Next, DNA polymerase starts copying the region between the primers. These copies can serve as templates to make still more copies.

Answer 2

There are many ways to do so. In plants the most common technique is to use a bacteria called agrobacterium. This bacterium performs genetic engineering as a natural part of its life cycle which forces the plant to send it nutrients, scientists have been able to remove a non-coding part of DNA from the plant and replace it with a bit of DNA they want to insert into the plant. The bacteria does all the rest.

There are other ways such as shooting bits of DNA into a protoplast or immersing the cells in a solution which increases membrane permeability or using viruses as vectors. Each method has its own merits and disadvantages.
