Plants have a different set of nucleotides in their DNA than animals do. Is this statement true or false? Why?

one more thing;
why do you get so many different proteins using only 4 nucleotides?

False.
There are only four kinds of nucleotides and these four are found in all living things.
Also, the four nucleotides can be arranged in endless ways, so the variety of proteins they code for is virtually endless.

To expand on the question about 4 nucleotides coding for a lot of proteins... The 4 nucleotides code for 20 amino acids. The sequence and length of the polypeptides formed by the 20 amino acids is basically limitless, and the sequence determines the protein, so there a lot of proteins and only 4 nucleotides.

true, and i believe it's probably something to do with plants photosynthesizeing. i should know this, im taking bio now.... sorry i cant help more
