A single human cell encloses about 1.5 m of DNA, containing 4.5 billion base pairs. What is the spacing between these base pairs in nanometers? That is, how far apart are the rungs on the DNA ladder?

How Do We know? How would you respond to someone who said, about biological evolution, “Oh, that’s only a theory.?

A single human cell encloses about 1.5 m of DNA. This length of DNA contains about 4.5 billion base pairs. What is the spacing between these base pairs in units of nanometers? That is, how far apart are the rungs on the DNA ladder? How many base pairs are there per millimeter?

The story of a process makes the facts easier to remember, but easy recall is not the true goal of the scientist. What is the real value of understanding a scientific process?

If life is based on information, what is that information?

The DNA in a single cell in your body contains about 4.5 billion base pairs. Imagine building a model of that DNA like a ladder with base pairs for rungs. If you make the rungs 1 inch apart, how long will the ladder be? Express your answer in miles.

Give an example of natural selection acting on new DNA patterns to select the most advantageous characteristics.

A group of scientists use carbon dating to date a piece of wood to be 3 billion years old. Why doesn’t this make sense?

How Do We know? The evidence is overwhelming in support of the idea that the Grand Canyon was dug over a span of millions of years by the erosive power of the Colorado River and its tributary streams. Is that a catastrophic theory or an evolutionary theory?
