I learned how to clone on Monday!
Of course, it's not for an entire organism, but I learned how to insert a gene from one organism into another and have it make copies of the inserted gene.
The basic idea is this:
insert a gene region into a plasmid vector, insert the vector into bacterial (E.coli) cells, incubate the bacteria and as the bacterial colonies grow, each one will have a copy of the inserted gene region.
There's a lot more to it...but that's the quick version.
