Sure, we don’t LOOK like a banana or even resemble one, so it may seem odd, but you would be absolutely right if you said that humans and bananas share 45% of their DNA! In reality, it shouldn’t be too shocking because when living things are broken down, we find that we all sharethe same basic stuff.
Just like buildings can look starkly different from one construct to the next, living things can come in all different shapes, sizes, and colors. But, when we look closer at a building’s intrinsic parts, we see commonalities in things like electrical work, windows, duct work, nails, screws—all parts vital to the bigger picture—but the combination is what’s sets the Eiffel Tower apart from a place like your home. Living organisms are much the same.
The DNA (or deoxyribonucleic acid) of all living organisms encodes the genetic instructions for the development and functioning of the world’s creatures—they’re basically the organism’s guide to living. Along with proteins and carbohydrates, DNA is one of three macromolecules essential for all known life forms and its information is stored as a code of four chemical bases.
