Do Trees and Plants have DNA?

Have your children ever asked you the tricky question:  Do trees and plants have DNA too?

Do you know the answer to that?

The answer is YES!  All plants, including trees, have DNA.  There are quite a few life forms that don't have DNA, but they are mainly viruses and are much too small to see.  All known cellular life forms, including bacteria, use DNA in one form or another.  The basic form/shape of all DNA plant or human is the same (double helix).  The code or sequence of our DNA is what makes each of us unique plant or human!  Many studies have found that we share between 50-60 % of our DNA with the Banana Plant, which would make sense since many of us are a bit bananas sometimes :-)

Researchers have found that in some cases a plant or trees DNA may be even longer then a humans.  One study found that the DNA from a Norway Spruce is made up of 20 billion base pairs, that is about seven time the length of a human's DNA which is made up of just 3 billion base pairs.
