How do the simplest bacteria relate to the most complex animal? A. all organisms have a double helix
B. all organisms share common DNA bases
C. all organisms have phosphate substructure
D. all organisms share common enzymes

Explanation:

As you probably already know, all of the cells in your body started from a single cell. That single cell then divided many, many times to turn into the 50 trillion or so cells that make up you. Almost all of the cells in your body share the same DNA as was found in that first cell

The components that make up the genetic code are common to all organisms! Same NUCLEOTIDES, same BACKBONE same BASE-PAIRS, same HYDROGEN BONDS! The instructions for making proteins (and traits) are in the sequence of nucleotides! These are the GENES that hold our similarities or differences
