1. A clone is a population of identical cells or
DNA molecules descended from a single progenitor.
Cloning is to make many copies of the same thing.
The cloning we talk now days is most of the time
the recombinant DNA technique in which specific
cDNAs (complimentary DNA copied from mRNA by
reverse transcriptase) or fragments of genomic DNA
are inserted into a cloning vector ((an
autonomously replicating genetic element used to
carry a cDNA or fragment of genomic DNA), which is
then incorporated into cultured host cells and
maintained during the growth of the host cells.
There are also two other types of clones called
reproductive and therapeutic cloning respectively.

is hard to know what those people think about
cloning themselves. Ego? Curiosity? Adventure?
Making a useful body part for later use? Hard to
say. Maybe we should ask someone who wants to
