DNA

I was fascinated by the following facts about DNA:

"Each cell carries the entire instruction book of one hundred thousand genes. DNA is estimated to contain instructions that, if written out, would fill a thousand six-hundred-page books. A nerve cell may operate according to instructions from volume four and a kidney cell from volume twenty-five, but both carry the whole compendium. The DNA is so narrow and compacted that all the genes in all my body's cells would fit into an ice cube; yet if the DNA were unwound and joined together end to end, the strand could stretch from the earth to sun and back more the four hundred times."

                  from Fearfully and Wonderfully Made, by Dr. Paul Brand

                  and Philip Yancy

The whole book is filled with interesting facts and uses them to draw parallels between the human body and God's church.
