During a gathering of entrepreneurs in Las Vegas one of the speakers was a brand architect at Lego. During his presentation, he handed each attendee six Lego bricks. Then he asked them to estimate the number of unique combina¬tions that could be created with those six bricks. This sounded like a trick question, so one attendee aimed high and guessed several hundred combina¬tions. That left him several hundred million short of the actual answer!

Are you ready for this? The total number of possible permutations—six bricks with eight studs each—is 915,403,765. Nearly a billion possible permutations with six Lego bricks!

While the number of possible Lego combinations is mind-boggling, it pales in comparison to the sheer complexity and potential combinations found within DNA. Here's why:

Legos have a limited number of ways they can connect. DNA, on the other hand, uses four different "bases" (adenine, guanine, cytosine, and thymine) that can pair in specific ways. However, the sequence of these base pairs is what carries the genetic information, and this sequence can vary enormously.

A single strand of DNA can contain millions or even billions of these base pairs. A gene, which is a specific segment of DNA, might be hundreds or thousands of base pairs long. The number of possible sequences for a gene, let alone an entire DNA molecule, is astronomically huge.

To give you a sense of the scale, the human genome contains roughly 3 billion base pairs.
Even a relatively short gene of 1,000 base pairs has 4^1000 possible sequences (4 because there are 4 bases). That's a 4 followed by 1,000 zeros, a number far exceeding the number of atoms in the known universe!

Possible Preaching Angle:
The information encoded in DNA is incredibly vast and precisely organized, making the Lego analogy seem in comparison. It serves as a powerful reminder of the awe-inspiring power and intelligence behind creation and is a testimony to the purposeful Creator behind life.
